Do this...Talk to her, be there for her, be concerned. Ask how she's doing, but don't try to push her away from him. Just make remarks, such as "I hate that you have to put up with that." Do that, but at the same time do not limit yourself to talking to other women. This'll workout in 1 of three ways. 1. The most likely scenario is that she'll just stay with him and get put up with being abused, 2. She'll leave him but it'll take her awhile and you'll get with her if you play your cards right, or 3. She'll leave him and say she doesn't want to date for awhile and then windup goign with some other guy and you feel crushed. So, why talk to her anyway? Well, see you have nothing to loose and a lot to gain, the trick is not to give her all your time. Don't waste time on her, meaning don't go out and buy her gifts or try to hangout with her; talk to her at work and if SHE asks to hangout with you do it. Just don't ask her.
