What to do if a guy cheats on his girlfriend with you?

Slap the guy and kick him in the balls and then tell his girlfriend what he did and tell her that you didn't know he was dating at the time. OR just don't have sex before marriage and the whole problem is thus solved. Seriously it's not rocket science. If you can't keep it in the pants then you are a slut.

I would talk with him about why he did that and try to find a solution for him, his girlfriend and me if it is possible to talk with him in a normal way. If that isn't the case, I would try to find out the phone number of his girlfriend and try to warn her. One point for this action would be to protect her from STD's.

If you really like this guy and want things to work out you need to make sure he talks things out with the first girl in order to make things work with you. f you don't want to be in a relationship with someone who cheats then just tell him you want to put the relationship off and find a healthier one.

I'm very sorry for the huge worry you are having. Well if the guy lied to you and you didn't know by any means he had a girlfriend, you should not feel guilty for what happened. The girl the guy is with has indeed the right to know what happened, however you also have the choice to let go of what happened and never contact the guy again, and be more cautious next time. I know if it hard to deal with it but everything heals over time.

Do what will set you free. You were not the only one involved in the act; after all it takes two to tango

The right thing to do is break up with him. It shows that you not only have respect for his girlfriend, it also protects you for future problems. If he cheated on his girlfriend with you, who is to say he won't cheat again? If someone thinks it's okay to cheat on one girl while dating another, he is practically cheating on both of them. Both of you deserve a better guy than him, and I wish you the best of luck finding someone who recognizes your worth, and I wish the same for the girl who was cheated on.

I wouldn't let him cheat on his girlfriend, and inform his girlfriend that he tried. I wouldn't want to have a guy in my life who didn't love me enough to satisfy him.

You should always try and think as if you were in her shoes. Try and think about how you would feel if someone cheated on you and push him to do the right thing and ask him to either stop cheating by telling her or by stop saying you

Once you find out about it, end it. It may not be what you want to do but even for your benefit it will help yourself in the long run. You deserve to be treated better than that, and so does the innocent girl that is being hurt in that situation. Never doubt yourself or your self worth.

Situations like that are hard to tell. You can only do what you think is right for you. If you feel happy with the situation it's your choice to stay or not. If you don't, do what you feel would be best for YOUR health, no one else's.

I would tell his girlfriend that he cheated on her because it's just wrong I would let her hate me to avoid him hurting her more

This is a very personal and complicated question. First, if you know that he's seeing someone else, you should wonder why he's so willing to betray someone he supposedly loves. That opens up a question, will he also so easily betray you? Does betrayal and infidelity bother you as an unhealthy aspect of any relationship? Also, if the guy is into you (for more than a one night stand), why is he unwilling to end his original relationship? What is his girlfriend giving to him that you cannot? Every situation is so very different. There's no right answer, there's no simple way to handle this situation. You have to ask yourself what you want, what you can absorb, forgive and accept per your own moral compass.

Have some moral integrity and tell him not to do that. Do unto others what you want others to do to you. You don't want to be the relationship breaker. Karma stabs you in the back. Chances are that if he is willing to cheat on his girlfriend with you, he'll do the same to you sometime in the future. We must do all we can to end this appalling vicious cycle of cheating.

if a guy cheats on his girlfriend with you, you aren't really to blame... why? firstly their relationship could have been going bad before he met you and maybe she isn't doing the things she said she would do or did when they first started dating and to some men that's a turn off secondly maybe he wants to leave the relationship but doesn't know how to because they have been together for some time thirdly he could just simply like cheating but have no reason behind it. but in all of his cheating and doing his girlfriend wrong maybe there could be come good at the end of the day you will never know unless you are curious enough and willing to try and learn from your mistakes you might just change the guy for the better and he could be yours.

If this situation happens, I think you should take some time out to think through what has happened. I then think you should come clean and tell the girlfriend in honesty what happened and how you also feel about the situation

Talk about it. Every situation is unique and there are no hard and fast rules in life or love! Questions are magic - they let you understand where that guy is coming from. Of course, after this event, you have to decide: will I be able to trust him? If not, you need to move on and let go of him and the relationship. If you can forgive and try to rebuild trust and there are enough factors that make you want to, then maybe you choose that. I like to think of relationships like bank accounts: our daily choices and actions either create deposits or withdrawals into that account. They either honor and build up the positive feelings with my partner or they tear it down. An action like lying or cheating will often zero out the account or take it negative. For most people, that means finding the coping skills to move on. Sometimes it's not the right choice for you, though, and that's ok. Be kind to yourself. Figure out what you need.

Honestly tell that girl that he did and you didn't know about it and you're sorry ..that guy doesn't deserve any of you

If you feel fine with being part of somethig like this you could keep on going. Though I think you are risking getting attached to him and losing him because he could decide to be faithful to his girlfriend again or you can become a part of situation where he decides to leave his girlfriend to be with you. In such case think about how you might feel, areyou willing to be in such situation ? Plus if he would leave her for you, I have heard that cheaters dont really change. So are you willing to be with a cheater?

And my personal experience,if a guy cheats on his girlfriend with you. Expect him to cheat on you with someone else.

If a guy cheats on his girlfriend with you, cut off all communication with the guy and contact his girlfriend and let her know sincerely what happened. Odds are she'll be upset with you, but its better than her living a lie. Do not pursue a relationship with the guy.
