I'm so glad to see you enjoyed your family all together. Congrats on being a Grandpa, again! That is wonderful.
Disappointment in the spouse, I've found is very common. You know they need to change for the better, but yet there is nothing you can do about. If they don't do that by themselves they will feel like they have been forced or made a wrong decision. When I let go of that, and let my H travel his own journey, he seemed to come back to me that much faster. I knew he was coming around when he started to 'mimic' everything that I had been doing...being polite, respectful, doing things FOR ME, repeating sometimes what I would say. I would agree, I felt the same way about my H, that I didn't know who he was anymore. And you don't, that women you knew is currently missing. When she is coming back someday, you will fall in love with that new person that she is. At least this is what happened to me.
I even told my H now that we are on better terms at the moment, that I didn't know if I could be with someone who couldn't grow and change. But now that he has grown and is changing himself, I love that about him. I hope this insight on my R gives you some hope to keep plugging away. You are still doing well and getting better and better each day.
Take care
