He contacted me out of the blue because he's having serious doubts about his engagement. He's miserable and for all I know, I was a last resort. He's desperate to feel better. I don't think I'm in much of a position to help. I doubt that things would be better if he'd stayed with me. I still care about him, so this is difficult. The unexpected difficulty is that whenever he contacts me, I open up and start thinking about other people. Sooner or later, this is going to get me into trouble.
