You don't want her out. In-house sep. is better because she can see your GAL. BTW, do some awesome GAL. If you're out of shape then get in the best shape of your life. Do things. Take up active hobbies. Be the best you that you can be. My advice on the boundaries is that she gets ZERO say in the plans your family makes. Why? Because she has stated she doesn't want to be part of the family. Ok, fine, but that decision comes with serious consequences. She must see those consequences. Plan some awesome things to do with the family but don't consult her. That's how she wants it.
