Ha ha. I have this person in my life who's sorta a friend (not a very close friend) and I tried to help him once, for a while and it felt like beating my head in the wall eventually yea. He does progress with his problem though on his own, it's just slow. Very slow sometimes. But I've eventually seen some major happenings and progress in his life about the problem. Unfortunately he's still on the fence about going to therapy too. So it's going slower than it could. Anyway so I have experience with this. I have way more experience with it in another relationship but never mind that one, that was a way more sad story with a more sad ending. With the above sorta friend though, I did stop in time so that was OK. I told him in the end what healthy boundaries I was going to keep about it and I've kept them ever since then.
