I cheated, should I break up with my partner?

First, you have to ask yourself if you still want to be with your partner. If you do, tell them what happened. Some people are more forgiving than others. Have a serious discussion with your partner to come to a mutual decision.

Everyone is different so I cannot say what you should do. What I can say is that it may not be necessary. Have you considered talking to them about what happened, apologizing, and making an effort not to repeat that mistake?

In my opinion, I believe it's best to be honest with your partner about what happened and as a couple decide where to go from there.

you have to be honest and let them know what happened. If you do not love your partner the you should or else it wont be an honest relationship which will lead to more problems in the future

That would all be up to you and how you feel. But just know communication is everything in a relationship. Try telling them the truth and try to work through it before resorting to breakup.

I think that depends on you. I would do a self-reflection and self-evaluation as to why you cheated on the first place. Was it because you're unsatisfied with your current relationship? Was it because you wanted to try out to see whether you could actually do it? There could be a number of reasons. I think it's best to start from there and what ever the reason or logic behind your actions, it you're able to rationalize and are willing to take all the responsibilities and work with the consequences, I think you would also be able to answer your own question :)

Tell him/her the truth, ask for forgiveness and the answer will depend on the results of your conversation.

You can try opening up to your partner and being honest about what you did then ask for his forgiveness. If he forgives you then there is no need to break up with him.

Confess about it to your partner. Apologize. Maybe they would forgive you and you can be together happily

You should ask your self what were the reasons for cheating you dont like him anymore, he dosent love you anymore. Will you do it again what is your stance on cheating? all this questions needs answers and in all of that you will find if you should brake with your partner.
