what about recruiting his friends and/or family? I know you said you staged an intervention, but I also know you can't do this alone.

I know you're what I call a fix-it, but some things you just can't fix. At some point you're going to be really sick of it all and build up resentment toward him. It's human nature to do so. To be even more blunt about it, this is your life and your relationship, not a case you're working on...

I'm so sorry if I came off all evil, but I've been there and I was just like you (according to the post) but I hit a point where I actually didn't feel anything anymore except resentment because I let him make me numb. I just couldn't even make myself react to his every up and down anymore, and thats a really sad way to end the relationship.
