GAL'ing is something I can't really do. I don't ever go out and have few non-work friends.
Sorry if you already talked about this, but ... why do you have so little time for yourself? Does your WW work outside the home? What does WW do on the weekends?
I was in a somewhat similar situation, in that I really did a lot around the house and w/ my kids. So much so that it felt suffocating and mothering to my WW, and she also felt very guilty about it.
I think GAL-ing doesn't *necessarily* require big chunks of time. I believe you can do little things to reclaim your independent identity. Just takes some creativity.
