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

If you love the person it should help guide you on what path you should take. If your cheating partner shows no signs of changing or being sorry, you should breakup. But if you feel inside you can trust the person again in the long run, then you shouldn't. This is a big decision that you should decide on your own. Follow your instincts. Don't feel the need to stay with the person just because you fear being alone. There are so many people out there that won't cheat on you and could potentially be a better boyfriend/girlfriend.

Cheating on someone is never okay, if someone cheats on you it means that for a split second they weren't thinking about your feelings. You deserve better

It depends on how intimate you two were. If it's possible for you two to talk it out by yourselves, figure out why it happened then go for it. If that isn't an option, try therapy, and if that doesn't work, maybe you two weren't meant to be.

It depends. Do you want and can you forgive her? Is it worth it? If so, make a new start and be happy. If not, break up.

Definitely. Once a cheater always a cheater. Plus I don't think you can love two persons at the same time.

It really depends do you think you can have a chance with this relationship or you think you should see other people it's up to you.

I would say in this situation, you should break up with that guy. Because, if you will not do this, you can't be happy in your life.

The best thing to do is talk through the situation and decide on whether you can trust that person enough to go forward. Always do what makes you happy, do not follow through with something if you are unhappy or unsure.

Yes. You deserve better than that, especially is you have given him/her more than one chance. Once a cheater, always a cheater.

Not necessarly. maybe you can both sit down and talk about what happen to see if there is anyway of forgiving each other to move your relationship futher
