She came home from his house this morning and told me that they got into a fight last night and he pulled her off the bed by her ankle and pointed a gun at her and threatened her. Obviously I am encouraging her to break up with him and even call the cops (I think it is TOTALLY unacceptable behavior, and it's not the first time he's threatened her), but she's on the fence. She said she feels guilty because she took part in the argument but WHAT. He also cheated on her about a month ago. What should I do to help her short from forcing her to delete his number, etc?
