Your heart must have leapt!
But, in all seriousness, sometimes people really, really want to change, but just can't embrace it, for reasons we may not understand. For example, how many times have we heard people resolve for a new year to give up smoking, lose weight, drink less or a million other decent actions. And, for someone who is as stubborn as your husband appears to be, it can be difficult to change lifestyle, or living patters, with "public" implications without that person feeling they are losing face.
When I worked for one particular organisation, I had one guy, who reported to one of my direct reports, who was (and I guess still is) incredibly talented, clever and personable, but change, of almost any kind, pretty much freaked him out. He would resist, up to an inch of disciplinary, until eventually I got fed up of it, and decided to talk to him about it, informally, but with a clear message that he would be managed out of the business unless he could modify his approach. With him, it felt like he would happily walk to the line marking change (metaphorically), but just
could not cross it. But, once backed into a corner and
made to cross it, he would enthusiastically embrace the change, because that was the new "normal". Frankly, it was exhausting for everyone around him, and used to make the guy very stressed. As an outsider it seemed bonkers, but to him, it was how he dealt with "stuff". Eventually, he agreed to undergo a period of specialist mentoring, in order to bring him back into line with his peers. He was like a dog with two tails, and when I left, he told me his life was transformed. (Actually, I think the guys is an extremely intelligent, high-functioning autistic, but that's only diagnosed by me, in conjunction with Dr Google.)
I know that's a great big ramble, but I'm trying to maybe have a little look at your husband's situation from an alternative angle. If your husband is like this other guy, you will have to maintain your stance, and constantly positively reinforce the steps he is taking, otherwise, he may revert back to his historic norms.
I do hope these glimpses of change are the new shoots of fresh change, and you both see the benefits.
