That is the trouble with abusive relationships. For some reason the woman feels that they are not good enough for anyone else and that no one else will love them because they are damaged goods. A lot of abusive relationships turn out with one of the two dead. I am glad she was able to get away.
Abuse is everywhere with women taking the most of it because they are seen as the 'weaker' part of the relationship. Men like her ex need to be treated like hardened criminals and not let off easily to send a message to society that this kind of behavior is not acceptable!
