Ironically right before I read this post, I got an email from H requesteing that we talk this weekend. He expressed his unhappiness and said he felt stir crazy. He wants to find a way to move on and have a happy, simpler life and specified "with you".
That's interesting, if nothing else. I agree with Telemark - it's best to wait and see. I think you can take away some positives from that, but be cautious. You're right - it is excellent timing that you have DB coach session scheduled for tomorrow.
Your GAL'ing is for you. Don't let up. It sounds like you're doing a good job of it. You're doing healthy things. It also sounds like your H is taking notice.
