LoneWlf, just wanted to drop in and say I am praying for your S (and you and your sitch, of course). I have a younger brother who was the exact same age as yours when my mom had an A and declared she was leaving my dad. My brother helped my dad for about six months trying to do all kinds of things to make my mom happy so she wouldn't leave (none of this was DB approved or probably healthy at all, but it's what happened). It was really hard for him, and it didn't help that he was the only reason she stuck around in the house at all. He was very upset when she never came around and remained resolved about leaving, felt she never really tried etc.

Anyway, it's been a couple years now. My brother and mom are coming together to visit me at the end of June. Their relationship has improved a lot from that low point and I'm sure he still has emotional scars as we all do, but he is doing well.
