I want my parents to divorce but I don't at the same time?

Okay. My parents are fighting a lot lately. I know my mom is miserable with my dad. Both of my parents have some pretty big problems. My mom is a druggie, but when she isn't high she cares. My dad is a control freak that I can never please and hates me for being Christian. If I make dinner, he won't eat it and make a sandwich. If I don't make dinner, he yells and throws fits about it. He leaves messes everywhere, but if I leave even one thing not done I'm in trouble. Get the picture? Anyways, I kind of want my parents to divorce because I think it may be better that way, less fighting you know and then I'd only have to deal with one of their crazy problems at a time. But I kind of don't at the same time. My mom is unemployed and wouldn't be able to support me, but my dad leaves for work before I wake up and gets back when I'm about to go to sleep and wouldn't be able to look after me. Also (and this sounds really selfish) but when my parents are picking apart each other and yelling, their attention is off of me and I don't have to worry about being in trouble. So I really don't know what to do or think about the whole situation...
