They really aren't as bad as people think.
The one I was in with DD was in an old country manner type house.
Huge place. We had our own room, lockable cupboards in the kitchen, shared the bathrooms but it was always clean and well looked after. There was a lounge area that all the mums could use, nice big kitchen, more than one cooker etc....
They staff were absolutely amazing and took control of everything that I needed. I was so, so scared. My XP had controlled everything. Every single aspect of my life was controlled by him.
I left with nothing too. No money, a banger of a car that was fit for the scrap heap only just managed to get us there....
I was there for three months, out of the area too.
No-one can get in without buzzing. They had two locked double doors. You will be safe there. If H tries to find you or goes there, they have panic buttons fitted, direct to the nearest police station too.
The staff will help you 100%. They are lovely caring ladies who will do all that they can to make your stay as comfortable as possible.
Anything that the DCs need, a doctor, school uniforms, money for things, they can contact people who can help you to fund these things and a GP that can come there, rather than you having to take the DCs out.
They will apply for a house with you, show you what you are entitled to. Help you.
Every.
Step.
Of.
The.
Way.
BUT - You need to leave to be safe. xx
