Mrs H - I had a friend in your situation and she managed to get out safely with help and careful planning.
Over a few weeks she got some clothes and toys out for her and the children . You know, like winter clothes than might be packed away now on top of a cupboard . She put them in a friends garage .
Then on D day, while her children were at school / nursery and her H was at work , about 8 of us went round with ours cars and helped her take all the kids and her stuff and some household things that she wanted .
We were able to dismantle the kids beds ( the ones from IKEA ), we took their mattresses , bedding, towels , a rug, curtains, all their clothes and toys . Basically everything from their rooms except the wardrobe.
We even got the washing machine ( which she wanted ) - someone disconnected it and we got it in the back of a hatchback # resourceful women
We got a lots of kitchen stuff in boxes . Books. Important paperwork .
She had NO money at all , her H controlled everything , so all this stuff was very important to her . Also she suspected that her H would destroy all her and the children's belongings once he found out they had left .
She has to rehome their small pets , as she knew her husband would kill them once he found out.
Everything went in the friends garage , except a few suitcases of clothes and toys. Then she picked up the kids and drove to a town a few hundred miles away, where her family live . She already had a womens aid place there . The WA worker helped her apply for benefits and got the kids into school / nursery .
She got rehoused quite quickly in a housing association property as WA get a proportion of their lets . Then she hired a van and drove back to pick up the rest of her stuff . She got a job, not well paid and only PT but still a job. And she rebuilt her life , free from fear .
She has no money at all , no job and little education. But she did it . And so can you .
There's help and support out there.
