In a relationship with an Alcoholic

I dated a woman I loved more than anything in the world. I gave her chance after chance after chance to choose me over the drinking. The drinking was wrecking our relationship. She would come home drunk and peed the bed, and hit her head on things because she couldn’t walk. She would drive drunk all the time. I begged her to get help but she said she couldn’t afford to get help. I got her a therapist and she went twice, but that’s the only help she tried to get. She didn’t think her problem was that bad, but it was. Her friends thought I was controlling for telling her I’d leave if she continues drinking. I told her I wouldn’t be around the drinking and she tried to come over when she was drunk anyways. Being in love with an alcoholic is torture.
