I Am Stupid

I was in a relationship for 6 yrs found out he was bipolar, I tried to help him, but, apparently there are addicticion to this disorder, he loved  **** and the company of other men and ladies. He was abused and abused himself, I could write a book.  Now he is in prison (happy for that). I do have a problem with drinking, I enjoy tha high, just like pot smokers,My new guy he loves pot. He treats me like I am tha problem and he never offers support, just utimatium. Looking for help
