My fault

Maybe it's my fault he's leaving, and maybe no body in the family will ever forgive me, but i don't really care.. I know it's going to hurt my mom, and siblings, but my pains gone. That's selfish, but oh well. He's put me through so much hell the past 10 years. I could care less if he leaves.
Or, Maybe i should be the one to leave.. I'm everyones problem, so if i leave, everyone will be happy.. Idon't know. I don't really have a place to go, but i can't stay.. I can't stand him, but i can't stand to be the reason for my family's pain. i dunno what to do.
