I'm not sure if it's something his therapist mentioned or not. I thought we were just friends - we would talk about work, our parents, cry on each other's shoulders, try to help each other through hard times. But I always encouraged him to work through things with his wife and to talk to her. He had told me a few months ago that his wife was jealous of our friendship, and that was when I first started to feel guilty, even though I'm not attracted to him or anything. I tried to talk to him less, put some distance, but I guess that wasn't enough. I worry that I contributed to his problems, even if it was never my intention.
