I know it is tempting to feel angry at H...I spent some time there a while back but it is pretty unproductive. I find that when people want to bash him, I just smile and change the subject...it works wonders and really shows that you have moved on from his drama!!
I am still wrestling with the "friends" vs "pretending he dropped off the face of the earth" thing.... Sounds like you are too!!
I know I have to be in contact with him 'til the house sells, after that I guess it's anybody's bet!
You are in a good place with everyhting right now so don't let others who don't understand your sitch lead you astray!!!
Happiness is like a butterfly: the more you chase it, the more it will elude you, but if you turn your attention to other things, it will come and sit softly on your shoulder.... (thoreau)
