Thanks for replying, everyone. It feels good to have my feelings validated. My heart just aches for him. He's requested that none of his family come to see him... including his 2 daughters. I don't know why he'd make such a request, because I think I'd want my family and my children with me if I were in his position. But, I'm not him, and I guess he has his own personal reasons.

I don't feel so guilty anymore... thanks to all of you. It IS ok to hurt for someone else, even if they've made a lifetime of mistakes. He's still a human being, and he was a part of my life at one time. I just wish he would try to right some wrongs before he goes. I guess that's out of my hands, though. Nothing I can do. It's just so sad.
