I cheated, should I break up with my partner?

In my opinion i believe so, there must be a reason why you wanted/ did cheat. I feel it is fair for the other person to know about it. Although breaking up is optional, you should talk to your partner about it and see what he/she thing about it and what has happened. go on from there

I think you should tell him or her and if the two of you can get over it and continue with the relationship, keep in the relationship

If you love someone then you should know not to cheat honestly. I know mistakes happen but cheating is a rather large mistake that is hard to forgive. Instead of just breaking up with the person you are in a relationship with, I would tell them the truth and be honest about what happened. Being honest could mean being able to stay in the relationship but also there is always a chance of a break up.

The best way is to come clean. You shouldn't break up with your partner if you really believe that you guys are worth fighting for. However, once you come clean it'll be hard for your partner to accept it and the choice is theirs to make.

You should tell him and, if he-she still wants to be your partner, decide between both of you if going on with the relationship is worth it.

That would be between you and your partner. There are several things that need to be considered here: why you cheated, where the respect for yourself and your partner went, the fact that after cheating, the trust in a relationship is lost and it is very hard to get back. In my opinion, you would be doing your partner a good by ending the relationship, so you both can do some soul searching and move forward in your lives. We all make mistakes, but what matters is how you let it effect you, and how you deal with the consequences.

Yes. You should break up with your partner, if you don't love him and that's what have lead you to cheating. Talk with your partner, tell him/her the truth.

I think you need to tell them and don't just break up with them and leave them wondering what they did, and then after that I think its their choice whether or not to stay with you.

No. You shouldn't break up with your partner. Instead, talk to your partner about what happened.

Why did you cheat? What do you feel now? If you're 1000%sure that your partner is not your type then do it but if your cheating went very bad maybe you need to confess and tell them how truly sorry you are and see what is the react then learn from the mistake.
