ADVICE PLEASE!!

Carla
HELLO ladies so I need some help with something.... I have a coworker who is going through some stuff and it breaks my heart. The guy she's married to is currently in jail and will be out in about a month or so (for DUI, I think it's like the 50th  DUI he's gotten) and she is having a nervous breakdown... She decided to leave him while he was in jail as there relationship isn't good at all... They have two beautiful children he's very abusive, an alcoholic, gives no F's about her and now his threatening her over the phone how if he finds out that there is someone else he's going to F her up to the point where no one will be able to look at here... I'm very nervous and scared for her and she's becoming traumatized... I advised her to get a restraining order on him but she also wants him to sign the divorce papers... And he doesn't want to...
