Ep, just wanted to stop by and say hi. The GAL is important, it's what has saved my sanity. It keeps me busy, allows me to explore things I would never have tried before, and most importantly I've met new people and been able to see myself through their eyes and not just STBX's view.
There are lots of shared parenting models out there, your mediator can probably help with that. When STBX first moved out he proposed one model, I proposed another, we finally agreed on a third. We are both flexible when we need to be. If you focus on the children, it will work out.
