I want to move out

How do you choose between your mum and dad? They both want me & Sarah to live with them, but how do we choose? Their fighting over us constantly, and it should be nice to know we're both wanted, but its horrible. To know that at some point, we're going to have to choose. To hurt one of them so much. I can't stop thinking about it, and they just don't seem to care. Well my mum certainly; my dad offered to meet up to talk about it all, but she wont even do that. Not even for me & Sarah. I love them so much, but sometimes i really feel the forget it affects us when they argue, our feeling are shoved to the side when it comes down to each other. So much hatred thrown around in my family, and im stuck in the middle of it all. I want to get away from it all. I need space. Id live by myself if i could.
