I posted this here because I hoped that someone would have experience with this dilemma. Sorry if it's in the wrong section.
My brother's girlfriend is planning to leave him. He's an all-round twat, not a very good father at all, too many things to describe that give him that title. I'd be here all night.
She believes (and I think she's right) that he's cheating on her with his exp, with whom he has a child (who was conceived from cheating on her before, no less. She took him back 
).
She's asked him to leave, he won't. So she wants to take her dcs and leave, but doesn't know where to begin. She's putting it all off until after Christmas. They're privately renting, he controls the money and she has none to move with.
She doesn't want to involve the police, she doesn't want to subject the dcs to that. Are there any routes she can go down to get herself out?
Will the council house her temporarily for something like this? If not, what can she do?
My family aren't in a position to help, my parents have a very small house and no room. Her family live abroad. Any advice?
