I broke up with my X because he cheated on me. I never caught him in the act but I knew he did. He even admitted to it, after I broke up with him. Well, after I broke up with him, he kept begging to get back together, so I did, but I just couldn't stop thinking about what he did, so I broke up with him again. He thinks I betrayed him the 2nd time because I broke up with him for no reason. I should have never taken him back the 1st time.
