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

It just depends on person to person. i do not think there is a ready made answer for that. Some people prefers to give the loved ones a second chance but some don't. But in my opinion giving him/her another chance if they are ready to admit the mistake, then giving a second chance would be fine. It is just my opinion, I am not a fan of breakups or divorces.

There are all sorts of conflicting issues with cheating. But, there is no right or wrong answer if you should stay with someone who cheated on you. They say "once a cheater, always a cheater" but the reality of it is you cannot simply categorize everyone the same way. You may want to consider, "Can I trust this person again?" and "Can I forgive this person for this indiscretion?" and let those answers lead you to if you should remain in a relationship.

Follow your Heart ! Everyone is human. If he/she rectifies himself/herself then i think you both can go back to being together

You have to decide what will make you happier in the long term. Starting afresh or fixing the relationship. Why did it happen?Was it a one Off? Could you trust them again? Could you be happy with them again. Can you get over what they have done and not constantly bring it up?

Ultimately, it's for you to decide, however, trust is a very difficult thing to grow back. Nothing damages trust like cheating.

I would. You don't need someone like that in your life. You deserve so much better than your bf or gf

In my personal opinion, when a boyfriend or girlfriend cheats I wouldn't give them another chance. I do understand that everyone makes mistakes and that's a part of life. But the person that you love and that is also supposed to care for you should not to go off with someone else as you two are in a relationship.

You should talk first of all it is key to understand one another , even though it may be hard you should try and explain things and come to a conclusion together

A break up due to promiscuity is a personal ideal. One of the biggest issues associated with cheating is a lost in trust in the relationship. You have to know whether or not you are willing to forgive and forget and work toward building your relationship stronger or if to call it quits and find someone who appreciates you and only you for all that you are.

That is entirely up to you. No one can tell you if you should besides yourself. It can be hard to continue to be with someone who has cheated on you. It is hard to be with someone who betrayed you the way that you did. If you can work past it and you want to work past it, than you don't need to break up. But if you do not think that you two will be able to work everything out, you may want to consider breaking up.
