Hey Sheila, I didn't know about the first PA and have some more thinking to do, but here's something that jumped out at me...
You don't have to make an instant decision to take down walls or jump into saving the M again. In fact, it seems much wiser not to. I would like to think that the walls will crumble slowly. Your actions will change almost imperceptably and one day you will realize things have gotten much better.
Give him the space and time he is giving you. The space and time to do the things he says he will and to try like he says he wants to. You don't have to decide yet. You sure as heck can give yourself a break from worrying about it though.
I think your H really sounds sincere, and although he has sounded that way before, let him show sincerity too. Tell him you appreciate his efforts so far, because you do. A little positive reinforcement on those would be nice.
"Thanks for the hug, H. Thanks for the nice thank you for the phone call. I appreciate those. I can't want to see what you are going to do tomorrow, maybe even something better? You know what things I want." If he asks what, mention the money in terms of "Please let me know as soon as you can. You know it's not the money, it's the timing." or whatever springs to your mind and then, drop it. Don't let him take it any farther. Seems to me you worked some wonders the other night by refusing to tell him why you were crying. Seems to me, he thought about it and figured it out himself and tried to do something about it.
