I have been in the same boat as you though I may had not let my feelings get to me as badly. I worked with a married man that I started having feelings for too. Feelings are feelings. But I didn't let that get to me, I would of like to have been friends with him but I don't think he liked the idea because he may had liked me more than he wanted to, too. I accept the fact we don't talk anymore, though he was a good supervisor/friend.

The fact he told you he was married shows that he is a good man to his wife. I know this would put a smile on my face because I would be happy for her. Accepting the fact you feel hurt and upset does help. Also distancing yourself from him more can help and going out on dates with men who are single. I know eventually you'll find someone....
