Yay! I am done! He called me tonight to tell me that he doesn't need help because he can drink moderately (2 OUIs, 60 days house arrest, 2 lost jobs, 2 bankruptcies) and that the real problem in his life is ME, because I'm just too critical of him. Needless to say, I hung up on him.
Texted him that his things are in the garage and he has three days to get them or they're being donated (I'm selling my house and I can't keep his crap around). Emailed all our mutual friends to tell them I booted him because he wouldn't get help for his drinking. Cancelled his cell phone line (on MY plan that I was paying for all along).
Done, done, done. Two and a half years of my life wasted. But, boy, I will never make that mistake again. I never knew anything about addiction before. Now I know more than I ever wanted to.
