Don't think for a minute that H isn't experiencing the consequences of his behavior. He is and time will tell when he will reveal them to you. Patience.
I completely agree with Wonka on this. I felt the same way, mdu: from the LBS perspective, it appears that the WAS is living the high life while we're left to clean up the messes and tend to the path of destruction left behind.
I've learned from talking to H recently that he was living in his own he!l during that time. And it was far worse than mine. It will also be much longer-lasting.
Good for you for declining the beach trip. Positive interactions are good, but I think your H can (and will) work for YOU a little in time. The fact that he asked you if you wanted to join - especially when you haven't been pursuing - is a good baby step in that direction.
