You are not alone I assure you. Even though we are electronic friends we are here. I would say look at the positive. He is educating himself . If he sticks with it or not is not in your control. You can set goals you want to see and either communicate them or not and let them be your own knowledge and of you dont see the results then you know what to do. From my PA perspective. I would communicate the goals to him and as long as they are moderately fair and as achievable as in are they healthy for recovery for both of you not just are they comfortable for both of you. I think and know a certain amount of sacrifice and change HAS to be in order for him. But regardless if the goals aren't met and they are evaluated on solid progress not perfection, then the fault is on his shoulders for not stepping g to the line and working.
