I've been following your threads for a while. I think you've done very well through some very trying times. Like you, it seems like I struggle more when my H is nice to me. That's when I develop expectations...and then end up disappointed.
From what you've posted, it does seem like your H has come a long way from where his perspective was, so what you were doing was changing the dynamic between you for the better.
I think you've got the right idea with going back to the gym and getting back to GALing.
