Hi, my wife's friend, who is married and has two children age 3 and 8 has been in abusive marriage for quite a while.
The husband takes drugs hard and soft (ongoing) and doesn't work (I think he is on disability for some reason) and is generally neglectful of his children. He has attacked her on a number of occasions. She has been saying she would leave him for years but has made excuses not to (needed to get passport (she's not British)), etc. Before Christmas he came home to find her with another a man and he ended up strangling her.
She didn't think she had any rights because of adultery. The mother-in-law (she has no family here) supported her son saying what she was doing in her husband's house was disgusting. (I told her to go to the police immediately but she never did.)
My wife and her friend went out for a night out in London and he was being absurdly paranoid. I understand it now she's at work and he's saying she can't come back to the house she's a gold-digger (they've been married for 10 yearsish btw) and just trying to take the house which I think was mostly paid for by an inheritance from the husband's father.
I think she isn't really aware of her rights and she's saying she just wants to leave forget the house leave the kids with him and she'd like to work and be able to see the kids when she wants to.
I believe she is likely clueless about the extent of women's rights in this country compared to her home country and she is likely to make a mistake, just wondering what she should do in the first instance.
