Honestly, the only reason I agreed to meet with him was to placate him one night when I ran into him and he was drunk, making a scene. He has almost everyone else either convinced he doesn't have a problem or willing to ignore it. It would be easiest for me if i did the same since he is so young and binge drinking is normal for a young, single male. At this point he blends in. And who knows, maybe how he is acting isn't the first big step toward a lifetime of the same.
The only reason I'm not ignoring it and staying around it is because it was making me miserable. As selfish as that sounds, my misery was my breaking point. And I'm happier with him out of my life. (That said, I'd be his friend again if he took steps beyond empty verbal promises to change.)
