On a practical note - does not the debts your W incurs on her credit card effect your credit? Why should you be paying for the OM's home? Just seems strange to me. If she wants to move out, surely how she pays for it, is her problem? One should validate their decisions, but you don't have to support it, financially anyway.
You are doing well, re GAL, and you handle the conversations very well with your W. I like, especially, your attempting to pre-empt anything negative she may say, i.e. the "too lates".
Keep it up! Keep in mind, always, that you don't control anything, except your reactions.
