I love my boyfriend, but I know he's cheated on me. I broke up with him, but some how we always end up back together. He told me he wanted to see other people. But the moment I started looking at other men, he got jealous and mad at me. He says he just wants me as a friend, but every time we're together we just end up in bed. But he cheats on me. Ugh. I love him, what do I do.
