IMO, your best approach is to accept her choice and go live your life. Stop worry about what she is doing and thinking and just be yourself. I like the idea of focusing on GALing and spending the time with the kids. DO what YOU want to do for YOU. Leave her be. Any changes that you do with an EXPECTATION that she will respond in a certain way will only leave you frustrated.
She want's out YET you are worried about the emotional distance. Why? the fact that she wants out should say something to you.
