My boyfriend or girlfriend cheated on me, should we break up?

Maybe you should sort it out first and then give them a chance to change. If it happens again, then maybe you should.

I would ask them if they're happy with you, be mature about it. It hurts when this happens as you give yourself to someone in hopes they will do the same. Be mature, and ask them if they're happy and if not, take the steps to move on, be the bigger person to admit that it will not work. Unless they admit that it's genuinely a mistake and they truly love you, move on. A person who cheats is usually unhappy in some aspect of themselves or the relationship.

I would say yes right off the bat but I won't assume that I know the situation. You know what went on. Was this person emotionally, mentally, and physically available to you when you needed him/her? Did this person make you feel safe? Did this person treat you with respect and dignity? If yes, then something really wrong happened in the middle that the two of you must discuss. If it can be worked out, great, but be discerning if it happens again. If no, then this person will probably make excuses which is NOT UP TO YOU to fix. No matter how much potential and goodness we see in people, it's not up to us to fix them when they do wrong. The must loving thing you can do for both of you, is to leave.

It's up to two things imho, A. Is s/he possibly going to do it again? and why did s/he do it in the first place? I can think of a mistake, unintentional and not related to this person personality, so it's not likely to happen again, but if it was intentional or the personality itself is not honest, sincere, loyal and devoted, and perhaps going to do it again, so it's a no-no for me. B. if A checks out (s/he's good, but made an honest mistake) so it's up to your forgiveness power and span, if you're able to really let go of that incident and totally forgive it, then it's cool, otherwise, it's not healthy for the relation to hold it as a leverage on your partner, to raise whenever you have a disagreement. If you can't let it go, then the relationship won't be healthy if you decided not to break up. Good luck

I was broken up with before cheated on. If they cheated, they knowingly hurt you. Try to decide for yourself if you see yourself truly forgiving them and trusting them. It will take a lot of effort and hard work and it will be different. Personally, I would not want to stay with someone who knowingly hurt me.

While cheating is the ultimate act of betrayal, sometimes mistakes happen and relationships can be repaired after cheating occurs. Take a look at all aspects of your relationship and decide whether or not it's worth fixing to you.

You should first sit together and talk about it. Was this a situation that unintentionally happened or the other? If you are both able and willing to talk about it with each other then you may come to a reasonable agreement. Whether that'd be going on your separate ways or continue with your relationship. Seeking professional help is also advisable.

Trust is a huge thing with relationships and if that person even managed to entertain the prospect of going for someone else while they are with you, then that tells so much of the status of your relationship. It's toxic. So yes, break up with them. It's not like break ups are the end of the line. You can take this moment to recover and also maybe you can rediscover and rekindle the relationship.

That's not good. This can be a hard situation for you to be in after this, due to an understandable lack of trust on your side. This is entirely up to you, as you know yourself best. Do you care about him, still? Does he care about you? Is it worth staying in a relationship like that? Is there anything else you worry about to do with them? It's hard to know for certain, but in time you will either forgive them or break up with them. Good luck!

First, it'd be best if you's sat down and spoke about this, adult to adult. Be openly honest about it and hopefully be able come to a civil conclusion.
