Please, tell me what to do. We have been friends since childhood, but 2 months ago we started dating as boyfriend and girlfriend. It was probably the biggest mistake we've ever made, because now I've lost both a friend and a lover. Everything seemed to be fine, and what happened was out of the blue: a week ago he said that he wanted to break up. We haven't talked since then. Now I don't know what to do. Tell me, please, how to cope with this situation.
