Thanks La and to all who answered with advice and support.
Yesterday the AH called his father (another A), and asked if he could come to live with him a while. His dad told him no. Additionally, he gets a letter from the State of FLA stating that his ex wife is trying to collect back support, and they are assisting in the investigation. So yesterday evening, I tried to remain detached while he sat sulking, crying, and very needy. It is amazing to me how I know that he has the OW on the side, and he could be doing alot to help himself, and yet, I STILL feel the urge to reach out.
However, the moment, I step away from the situation, I get angry. I feel a mixture of anger, pity, and guilt...It is truly awful.
