Oh hon, I feel your pain.
Vent all you like, that's what these boards are for. There are a few things I have learnt whilst being with my A b/f.
1) Most addicts don't love themselves. This makes it difficult for them to love anyone else. This isn't personal to you, it's personal to them.
2) When As say nasty things to you, they are really saying those things to themselves. i.e. when your Dad says you're stupid, he's really talking about himself. If you don't drink, you are displaying qualities that he would like to have. I have never met anyone with an addiction problem who is happy.
Keep coming back here, try a meeting and, most importantly, don't keep things bottled (oops!) up.
Take care.
