I don't know of anyone but maybe you could contact WEAVE and they could offer you some support.
I was lucky... it was just me, no kids... when I finally left my abusive husband who would yell and scream at me all the time. Eventually, he threatened my life and that's when I left. I rented a room from a friend and went to WEAVE for a restraining order.
I really wish I could help you but I don't know anyone renting or anything... but contact WEAVE and perhaps they can give you a lot of help... or advice... or get you in a shelter for now. I wish you the best of everything.
