Welcome ! Well, I loved my ex too, and I wanted to help him too-just wabted him to get better...but that was not my job , it was his - and he didn't want to (although I spent many years thinking it was my job!!). Please keep reading about alcoholism (as others have said, the stickies are a great place to start) and understanding the basics of addiction and codependence: the three C's are a good start-
You didn't Cause it, you can't Control it and you can't Cure it (I think I got those right !).
Hugs and peace to you!
