Hi SD, Welcome to the message board. Sorry to hear about your situation but I think you'll be glad you found us. You'll find a lot of support here.
Your H's reaction of going through the cycle of coming closer and pulling back is very familiar to a lot of us here. He's in a state of confusion right. Just be prepared for the cycle.
I think you have a good start on GAL'ing and you're getting good suggestions. Look for things that are going to put that extra spring in your step. There's not a one size fits all recipe to GAL'ing. For some people it means curling up with a good book, for others it may mean going skydiving. Look at it as an opportunity to try new things. Once you are able to brainstorm, I think you'll find it will build on itself and start to snowball. Concentrate on healthy activities.
