I'd be devastated if I were in your position. Cheating has never sat well with me. I have ended every relationship in which someone has cheated on me. Everything before the act of infidelity becomes a lie and a waste of time when I learn the other person has been unfaithful.

After 5 years though, I don't know. I've been with my current boyfriend for 3 years. I can say I'd leave him if he were to ever cheat on me, especially because he has accused me of cheating in the past, but I might try to stick it out like you're doing now. I tend to give people the benfit of the doubt, except when they cheat on me.

Truth is, you can't erase the fact that he has cheated. You have to decide if you're love for him is enough to motivate you to stay in the relationship and work things out. Is you love enough to get past the hurt and the doubt that he may cheat again?

It wouldn't do either of you any good if you're always going to hold it against him while remaining in the relationship. I mean, what would it take for him to prove himself again and even after he were to prove himself again, would you be okay with then?

I wish you the best of luck in whatever you decide.
