I wonder just what you mean by the !!!! Oh, I am so glad for you that your D is well and truly busted!!
I know how you feel, my H seems to be doing so much better, but my brain can't get wrapped around the fact that he is being nicer, and is home more, and is talking to me the way he used to, although he sometimes half-heartedly says he isn't sure I really love him. He seems to be enjoying my company more, and sometimes talks about the future, as though he feels we have one. It's that dang old insecurity that does it, like you when he goes to work, or you disagree. It will take time for you, your H sounds like he is really really trying, and is committed again to you.
I know your painting is probably lovely, and you will make the garden look very nice, too, maybe a good place to sit in the evenings with your H watching the little one run around, and maybe a couple more little ones eventually.
