Hope the move is going well for you! Sorry to hear about your stress fracture. Ironically I almost hurt myself similarly this morning. It was still dark when I was running and I hit a hole and caught myself just in time, just a warning for me I suppose.
He is still a very involved father, in fact even more involved lately. Ironically I used to volunteer a lot for the local basketball league and he told me that I was spending too much time there and not enough here, so I scaled it back and only serve on the Board now. He has since taken my original commissioner position and coaches our sons two teams. The very thing he said I was doing, he is now doing (there is a pattern forming here, I see)
I really feel like it is #2, the mid life doldrums. He basically said "is this all that there is".
I think you are right, he wants the marriage and to be able to do whatever he wants with no discussion or question from me. Obviously I can't do that, he can't set my boundaries for me.
