A friend is going through a really nasty break up... I'm not her closest friend, but really do care about her and her children. Things seem really unpleasant, with her ex wanting half custody. She has raised the two children, and been a sahm during that time. He is cutting off access to finances etc. Is there any advice or practical support I can offer...? I am useless at knowing what to do, and don't want to patronise her. I want to do something though...
