Drained,
Call Domestic violence hotline in your area (I know your not in Jacksonville) There are a lot where you are. Im not saying your going to do anything, but find out options, a one room efficiency would be better...you just wont see it that way until you know.
With the economy the way it is theres more of this, and trust me no matter what you want to think, the girls know, if nothing else start watching them how they treat each other, other people...things they see, attitudes rub off
