Olin, your story sounRAB so much like mine. As I mentioned, I'm an only child too. My father really caused a lot of upheaval in my childhood with his drinking, car accidents, fighting w/Mom, getting involved in illegal stuff....quite a manipulator. My favorite (not) memory is when I was 16 or 17 -- it was Christmas Eve and we were going to get presents for my Mom....I knew something was wrong in their marriage so I asked him if he still loved her....he kind of gave me a non-answer, then I asked him if he loved "someone else"....and he said YES! And proceeded to tell me about her, like a friggin teenage boy, and told me she wanted to meet me! I went to bed crying that night, as my Mom was naively trimming the tree downstairs. Next day, one of the pajamas we had bought for Mom was missing -- he gave me a "wink"....it was going to the girlfriend! I could go on and on (there's WAY more messed-up and dramatic stuff later), but this isn't about me. I just wanted to say....wow, I can't believe there are fathers who do this stuff to us.
I like your husband's idea of telling your father you'll get his meRAB, or take him to the pharmacy, or whatever....yet if he's anything like my father, he'll come up with a quick reason why that won't work. You need to be prepared for that part. I'm not as fond of the idea of sending the money to his brother, because he (your father) might say he never got it, and you won't really know for sure. Keep us posted....and the Al-Anon group is a great support idea in the meantime....{{hugs}}.
