You might want to add Theresa Hackeling - the Dr. She admits to giving Nancy money. You also might want to look at how many of them had Nancy and the kids over for dinner - while maybe they did not contribute money, they may have provided support in different ways. Just a thought.
I just want to add my two cents into "his not giving her money". I have two brothers both divorced. One ex sister in law is a pro at getting people to feel sorry for her she lives off people. She doesn't have a job. When people catch on to her she moves to a new community and starts again. The other sister in law called and asked my brother to pay a bill for her. He gave her the money then she called back and said she didn't get to pay the bill because she had gone shopping. I'm not saying that Nancy participated in this type of behavior. I have just seen it occur. They also tell their friends and families how my brothers don't help them.
