Only time will tell. Why try to determine the future?
Feeling resent about positive change in the A is not uncommon at all. I felt it when my mother got sober because I had nothing to do with it and I had tried for years to "help" her. Then all of a sudden she does it without my help? Boy did I feel like a failure. To top it off she was different. Not drunk or angry any more and I felt like I didn't know who she was anymore. Turns out I didn't even know who I was because I was so focused on her.
I also felt resentful every time she started making positive changes because I had seen he do it so many times and then go back to drinking. I didn't trust it. I was fearful. I learned in recovery I was ruled by fear.
So yeah, just keep working on you. Let him work on him and it will work out how ever it's supposed to work out.
