Well himbeere my husband has had some good days but mostly just slipping back into doing it and then saying he’s feeling disappointed in himself. He says the same as yours that he doesn’t actually enjoy doing it much anymore as it’s gone on so long, but it’s a habit, he doesn’t even know why he goes to get it ,he says it’s like an urge he can’t stop himself from going. I don’t see what I can do because I’m at work myself I can’t be there all the time, and even if I could I think it would be torture for both of us trying to supervise someone 24 hours a day, and I don’t want to live like that. So for now I have to try to be optimistic when he’s done well and then suddenly massive disappointment when I realise he’s doing it again. He even acknowledges himself how much it changes him, although I read other people saying that it’s typical of a comedown feeling sorry that they’ve done it once it’s too late, all the regret, but it’s hard to accept as when it’s your own husband you just want to believe them, you want to hope it’s genuine and they won’t do it again because they regret it so much.
It honestly is just true that there’s only so much that anyone can put up with.
