i didn't move out because of this, but my brother and i had a terrible relationship. we were so evil to each other, doing mean things, we even got physical a couple times (which is scary cuz he is much bigger tham me!) and said really hurtful things to each other, but the moment i moved out, our relationship completley changed, he was even sad when i left, and now we hang out a lot and we're super close. so yes, moving out really is the best thing in the world.
