My god, it sounds like being in prison.
These sound like the women Erin Pizzey talked about - women who were in their own way as bad as their abusers, who thrived on a co-dependency of abuse and violence, and were incapable of living without chaos and aggression in their lives even when they were offered the chance of a fresh start.
Of course if you have led a fucked up life and existed in a cycle of bullying, power, fear and aggression from start to finish you can often end up like this, and it's hard to know where the victim stops and a new abuser starts. It's just a shame they have children. 
But then she was totally villified and discredited by many women's rights activists for daring to say that and I suppose I will be on this thread, too. It seems women in DV situations must always be painted as perfect, saintly and blameless which of course very often they are. But not always.
I am guessing if these women are as awful as you say then they may be known to the council/authorities, probably repeatedly losing the homes they are placed in due to anti-social behaviour. Hopefully you will be considered for housing ahead of them, if they have 'form'.
Keep your head down, stay safe, and hold onto the fact that it won't be forever. I wish you strength and some good luck.
Incidentally, if you are given priority for housing on the basis of fleeing a DV situation, what happens if you known to have returned the the same relationship and the abusive (or apparently abusive) partner moves in with you? Do you lose that house?
