How do I get my boyfriend to trust me? When he broke up with me, I made a mistake and slept with a close friend at the time. After my boyfriend and I decided to get back together, I decided to tell him what I had done. We fought, and finally fixed everything. Yesterday he said I had done it in his bed, with that other guy. When that is not true at all. He won't talk to me, and I am going crazy because I don't know the half of what's actually going on, or where this came from all of a sudden, after over a month, almost two. What do I do?
