Looks like you are starting to see a few positive signs from H. That's a good thing, in any situation in life, if there's improvement over deterioration, it deserves to be acknowledged.
You are right to have feelings of anger and resentment. I think it's important to feel those things, but not let them consume oneself. It's a narrow balance to maintain - part of us wants to retaliate, another part wants nothing to do with the other person, and yet another part wants to put the past in the past and look to a better future.
Where you go from here is up to you, as it is for all of us LBSs.
I'm nowhere near piecing, but I would tend to think that you might start it by rereading your last paragraph in the post above and later, once he has shown a willingness to continue with his own improvement and if you so choose, finding a way to communicate that to your H.
