WCW- For what it's worth, I think I'm seeing a glimmer of a pattern here. Not just for you and your sitch, but for many LBS's, myself included. I think you have seen many small babysteps forward with H. He is showing a little interest in being part of your life because he's starting to feel left out. (so KEEP UP going to events solo that you would normally take him with, no matter if you're lonely! You got me!!!! )
Anyway, the pattern I notice is that as LBS's start to see these positive signs and start to feel like the WAS isn't leaving as fast as they thought, the LBS starts to feel safe enough to feel that anger sneaking in. And it's not a conscious thing, it just kind of happens. You start to feel safe enough to admit your resentment, if just to yourself.
When I was leaving Alaska and H was CLEAR about there being no future between us. I felt very little anger towards him, considering. I felt like if he snapped out of it, I could forgive him on the spot and never look back. But, now that he has apparently snapped out of it, I'm facing the new obstacle of dealing with those feelings of anger that I didn't think were that strong in the past.
So, on the bright side, maybe these angry feelings (that you call a bad PMA) are just a natural progression of the path to rebuilding your marriage?
And please be kind to yourself and remember that it is only right to FEEL ANGRY! In fact, it is inevitable. And eventually it is only right that you be able to confront that anger with H. Perhaps not now. But, FEELING resentful and ACTING resentful are two different things. You control the second, but not the first.
