You said he kicked her out? Did she take the child when she left? That's grounds for something right there. She needs to contact a lawyer immediately to find out her rights and what she is able to do. He can't kick her out of their house. She might actually be able to use that against him and have him removed from the home and then put a restraining order on his dumb ass.
Now, If she left that child, when she left, he can get her for abandonment.
As long as she didn't sign a prenup., she'll be able to get alimony and child support if she takes it that far. I wouldn't count on it unless she's a really strong woman(those are few and far between).
Just be there to support whatever decision she makes and try not to talk bad against him. Woman can be very blind when it comes to the men they love and exspecially after children come into the picture. Don't risk your relationship with her and just let her know you are there regardless of her decision. I wouldn't let her know you posted her business on the website either.
