I cheated, should I break up with my partner?

That is your call. Some people choose to be honest, others break up, others just don't tell. How would you feel if your partner cheated on you and what would you want can be a hint what might work. Consider your own feelings, the strength of your relationship etc.

If you have strong feelings for the other guy/girl, you have already broken up with your current boyfriend/girlfriend emotionally. That is just a fact... I think that you should talk with your partner about that. If you feel really bad about what you did and your partner would be able to forgive you, maybe that will gonna be fine. I wish you luck.

Confess that you cheated to your partner and if she/he wants you to break up then you can break up.

yes you should, its bad when you cheat on someone who really loves you, it will be hard for the other person but he/ she will be okay

You should have broken up with him or her before you cheated. But to answer the question, yes, you should.

Talk to him/her and explain why you cheated. if things go wrong, you should leave him/her but tell them everything and listen to what they have to say also.

You should talk to them about it, and explain how you feel. Accept that a break up may be their choice.

If you cheated, a way of focusing the issues would be to try to determine the real reason why you did in the first place. Giving and having a clear booster on why yo acted the way you did, will help you decide where to go with your current relationship and how to act upon it. Nevertheless, it is your partner's right to know you cheated and is their decision as well to think about where the relationship is or isn't going.

You should only break up with your partner if you dont love him/her anymore. If you still love him/her then dont break up.

Definitely not, you should tell them what happened. Do not make excuses for your actions, there are no excuses. Talk it out, if they decide they can not forgive you then they have the choice to leave. You should never leave someone with no explanation, look at the situation from their point of view.
