Help [sad] need some impartial advice as I'm torn here. I've just found out my boyfriend of a year cheated on me about 4 months into our relationship. He supposedly didn't sleep with her but he dated her and kissed her behind my back and openly lied to my face at the time. It was 3 dates then apparently he realised he loved me and called it off with her [hmm] At that point we had definitely agreed to be exclusive, at least a month before he began seeing her but we were taking things slow and hadn't said we loved each other or anything. We hadn't met friends or family but as far as I was concerned we were exclusively dating. Since then we've become more serious, things have been great and he's recently met my children and is absolutely wonderful with them. Our relationship has developed so much since that point but I feel like it's all been a lie now I need to leave him don't I? [sad]
