Bunches, I'm not caught up on your sitch, but just reading pg 6 of this thread I wanted to comment. If D is the route you go, I hope your WAW comes to her senses if ya'll do the educational classes on the affects to the children. Being a parent, you know only you and W know S best.
A friend of my WAW was once engaged to a guy who had a daughter that was special needs. She often vented how it was difficult to raise his daughter. I don't know if the daughter played a role in the future groom's decision, but out of the blue he called it off with my WAW's friend.
