I know this isn't the right kind of thing to ask for on here but i can't seem to find any answers online. It's to do with a family situation so really looking for advice for someone who may have been through the same situation.
My sister in law is being treated badly by her partner (mentally not physically) and is very ill at the moment. She is in hospital and due to be released (I think) and is still being treated like crap by her partner. I don't want to go too much into depth with the situation but she is on the verge of leaving him.
They aren't married but have been together for about 15 years and have 3 kids (13, 10 and 4). They have a mortgage together (in Scotland) and she thinks that if they split up, she will have to leave with the children. He works but she stays at home. Does anyone have any advice on what she can do?
