Nice going with the GAL work - sounds like its paying off in terms of attitude.
The ex contacts seem a bit icky. Have you thought about screening out her calls/emails? My concern would be that she splits you and H (in his mind, at least). In your mind, I'd suggest seeing you and H as united, with his ex as an outsider. I know its more complicated than that, but sometimes its more effective to summarize.
Sending good thoughts and a prayer for your afternoon interview!
