Just another side of the coin, some of my WAH's family contacted me after BD to tell me they were sorry to hear the news and hoped I was OK. Of course that was very nice and caring, but you know what? It made me feel worse! It's like they took the time to break up with me too, if you know what I mean.
I guess it should be comforting that they care, but it hurt to see their messages of pity, and really made the split seem much more real and permanent.
So, maybe be a little happy that you haven't heard from them. Maybe they don't want to "break up" with you.
