If you are allowing the cheating to take place, it's likely that there will be some drama and you will be involved. Hearts will be broken. To prevent this from happening, it may be best for the guy to express his feelings to his original girlfriend. This is only a suggestion. It may not be a great option for your situation, whatever that may be. I wish the best for all three of you! ♥

Tell him you are not willing to continue the relationship and tell him it is bad to cheat on someone that really loves you and cares for you and does everything for you

Talk to the girlfriend and inform her on what has happened so she can get out of that relationship, also inform her that you had no idea he was dating her

Try to put and end to it. You are probably hurting his girlfriend, but yourself as well. At some point the guy has to choose between you and his grilfriend. If he does not pick you, you will end up hurt. If he does pick you, you might encounter trust issues. if he cheated once, he might do it in your relationship as well. He should communicate to his girlfriend about what he wants. If he wants to be with you, its only fair to break up with his girlfriend. I think in the first place this is his choice and he should try to come to a respectful solution that works for you and the girlfriend.

At first it might seem all nice and lovely but honestly that's not right. He's not only hurting her but there's a high chance that he will hurt you too in the future. Staying loyal and committed in a relationship is very important. If he loves her, he should stay committed to her and her only. But if he's not happy and wants to continue with you, it's for the better that he lets her go. He's not treating either of you right. It also shows how much respect he has for her. If he can do that to her, he can do that to you too.

I think you should talk about this with your boyfriend, you deserve happiness in the right way. If you think you are making unnecessary fights and havoc then girl, I think you can cut it off then go away but if he really is your happiness then you deserve to be happy. Communication is the best way to figure this out. Cheating is not a good thing, and the both of you should be honest to the people around you. If he can cheat on her, then what if you get together, that gives him another chance to cheat again. Lessons can only be learned if they get affected so much. Becareful girl, but you deserve happiness. We support you here.

If you find out that you are the "bit on the side", ask yourself how you feel about that status. The ask yourself how you'd feel if you were the one being cheated on. Honest answers to those two questions will usually give you a pretty good idea what you should next.

You stop it and talk to him about it, you know it's not right to do it to anyone and no one deserves it.

don't do it because he could use you for your body just to get back at his girlfriend and maybe even just brag about how he could get wit you any time to everyone

You tell him he must tell his girlfriend and be 100% honest about it. If he truly wants to be with his girlfriend, he has to be honest with her.

Try to step back and view the situation from afar. First think about what is best for you, and take care of yourself

Depends if you know about it or not. If you didn't know about his girlfriend, you cannot blame yourself. If you knew he has a girlfriend, you just lost one big thing: your dignity.

If a guy cheats on his girlfriend with you, the best thing to do is remove yourself from the situation. If you remove yourself from the situation you are no longer putting yourself at risk of harm and you are also helping out the girlfriend by no longer involving yourself with the boyfriend. It may be hard if you are attached but there is a saying that once a person is a cheater they are always going to be a cheater. Put yourself in the girlfriend's shoes and see what they might be feeling if you are still unsure if removing yourself isn't the best option.

This is a horrible feeling and has happened to me before. A guy used me and I didn't know he had a girlfriend until afterwards. I dealt with this in the best way I could by one, telling his girlfriend what happened. She wasn't happy with me and thought I was lying because I had a crush on her boyfriend but then she realized I was telling the truth and we became close friends. Then, two, I made sure to tell myself that none of it was my fault. I didn't know he had a girl friend so there was no reason for me to assume he did. He was an honest guy, or so I thought. Do his girlfriend a favor and tell her what he did. She may not be happy with you but you are still doing a great service to her by doing this. :)

If a guy cheats on his girlfriend with you then you have two options. The options depend on how you feel as a person. If that's what you're into, then that's on you. If you want to keep it only known between you and the guy, that is also on you. If you feel like you're doing something wrong then you should just tell his girlfriend as soon as possible. (What I would do) Even if you think it's okay, it might not be okay to her and it's also not fair to her if that's the case. If they've been together for a long time it's even more important. If the guy cheated on her with you, he probably will cheat on you with some other girl as well.

If I ever came to know about this I would leave that guy then and there. Because a guy who could cheat on some other girl with you and also cheat on you with somebody else. It's very simple that a person can never ever give up his/her habit. And if that guy is habitual of cheating on girls he's always gonna do that with anyone and everyone. He might act as if he's guilty but you should really have a close look into his personality. And when you choose to stay with such a person even after knowing all this, you are doing one of the biggest mistake of your life.

I had this happen to me, it was with my ex. Just talk to him first and tell him how you feel. If he acts up, maybe start talking to the gf but don't run to her and say he's cheating. Also make sure you have evidence that he is. The girl may think you are lying so try to befriend her. If that doesn't work, cut it off with the guy. You don't need someone who wants to hide you away and you don't want to be his side hoe. Remember to do whats best for you

One question to ask is, "did you know he had a girlfriend?" If the answer is yes, then ask yourself why you allowed it to happen? If the answer is no, forgive yourself and end the relationship if it has not already ended. He knew he was in a relationship so you know he is not trustworthy. Try to be careful about the people you allow in your circle. Next time ask about a significant other before entering into any type of relationship, even if it is just a dinner date. It will not help his girlfriend to tell her. The best thing is to move on and distance yourself from him.

First of all you tell him never to contact you again and respectfully tell his girlfriend, that would be the best approach so that she doesn't blow up on you and think you knew, many women may lose their reasoning when they've been cheated on and take it out on both the mistress and her partner, show her that you were innocent and unknowing... If she still breaks out, don't be too offended and just stay out of her way... Although that would only apply if you didn't know he was in a relationship at the time, if not, tell her and apologize as I said before don't be too offended, if she blows up, just stay out of her way. Good luck

Well this question really have a lot todo with you and how you feel about this subject inside. Each person is going to react differently with this question based upon their up bringing and based upon their religious beliefs. So, I'm going to say if you didn't know he had a girlfriend while you were with him, it probably would make you really upset with him and possibly cause you to quit seeing him because he did not value the other girl and he did not value you as a person. He violated you as a person and took something from you that you might have wanted to give to someone special. Instead, he mislead you and slept with you for his own personal gain. So, you probably are better off without him, and you deserved to have someone who love you for you.

If you discover that you are being used to cheat on someone, you could contact the girlfriend and talk to her about the situation. You could also call out the guy, but the other girl might be confused about your role in everything so it might be better to talk to her as well.

In my opinion the best and only way is the true. Tell her girlfriend but don't do it aggressive. All of them needs to talk and expose the arguments, a lie only will break all the relationship between you, him and her girlfriend.

You stop him and tell his girlfriend. She deserves to know and you deserve more respect than that. That is the best thing to do.

Tell his girlfriend if you regret it. If you don't just don't do it again. You should confront him..

i would probably be wondering why did i sleep with a guy since i am straight :p well if you are a female , you should just tell him it was a mistake and what you two did is wrong in the right of the girlfriend and he should either take care of her or let her go but not foolish her by cheating on her

Never have contact with him again. He is not good for you. It will not end up well. Instead find someone who doesn't engage in that type of behavior.

You are the best at knowing yourself, if you truly have feelings for him then take action. At 7 cups we always encourage honesty, and you have to ask yourself how would you feel if you were the other woman.

Push him away, tell him that what he's doing is not good, and then tell his girlfriend about what he did. People should respect more their relationships, seriously...

If you feel guilty about it, perhaps you should confront him and tell him to break it off with his girlfriend, instead of lying to her and deceiving her. She'll obviously be very if she found out through other ways. If he refuses, maybe you should go tell her yourself and explain that you weren't aware that he had a girlfriend.

first of all, you should know that it is wrong to cheat, and try standing in his girlfriend's shoes; ie how betrayed and hurt she must feel if she was to find out. then the right thing to do is to confront his girlfriend and tell her exactly what happened and let them work their relationship out on their own. next, if he happens to leave his girlfriend for you, then you'll have to ask yourself whether you should be with a guy who has cheated in a relationship, especially since it's recent. if he's willing to cheat on his girlfriend with you, there is a good chance that he will do the same thing to you, if you were to be together.
