"OK, any takes on how you explain that? You divorce your wife, have a GF and then what...? You play happy family again? This just aint normal. At least not in THIS country."
This is very common, I believe, when the WAS does not really want to close the door. In fact, I think it would be unusual for him to make it a hit & run event.
My H called my friends & asked if he could join their invitation only party so he could be with us at Easter.
I still get the feeling that you're leading the charge & it'll probably be you who goes for it, because he's just not that interested in getting D'd.
Anyway, none of this surprises me, seems pretty script.
