Me and my boyfriend have been together for almost 3 years and we have a daughter together. Well I just found out that he cheated on me 2 years ago with a girl that he told me he’s never been with.

I’ve also caught him, not too long ago, messaging girls on a dating website asking for pictures. I don’t know if I should leave him or not. I do love him but I’m not the type of person to stay with someone that has cheated. What should I do?
