i dunno, having ANYONE "go at" my daughter because they are nastyass drunks would be sufficient motivation to get out. she's learning to TAKE abuse. she's learning not the rock the boat. she's learning that we can't take action in our own best interest unless it's convenient and well timed.
if the house burned down tomorrow, you'd HAVE to find a new place. and you would. you CAN make it work....but are you ready?
as for other party....as long as HE is not your reason for making changes, and as long as there are no promises and dreams of happily ever after cuz HE'LL make all your wishes come true, you should hopefully avoid going from the fry pan into the fire.
