Unless the police can guarantee that they will arrest him promptly and put him in prison for many years, the girl has a valid reason to fear for her life and more so for the life of the child.

Just agreeing with you, Helene. Sometimes I think the woman is staying because she has issues. but in this case I can see where the fear is very valid.
