You know, I felt that way about my ex-, too, until I found out he died. (Injuries from a motorcycle wreck. That man never would wear a helmet.) Much as I was really, really pissed at him at the time (and for many years after) I have to admit we were both young and really stupid. I had a hand in the crazy that ruined us just as much as he did. (Now, the aftermath, when he didn't take care of his responsibilities is all on him, but that's another conversation.) Anyway, wherever he is I hope he is at peace and knows I loved him best as I knew how.Having been married and divorced, this is all you need to have said.
Edit: Huh. Will you look at that?? I appear to be mellowing in my old age.
