I wouldn't' take it out on her. If she's in an abusive relationship then her husband likely has control issues and is trying to dominate and control her. It's probably hard for her to confront her marital issues cause she's afraid to lose him if she does. She also might be afraid that if she gets close to you or mends things that the subject will come back up and he'll see that as a threat and use that against her. If he turns her against ppl and she lets him, then she's convinced herself that he's more important than anyone else and so anyone who challenges her threatens her relationship with him. On top of that, she could be emotionally unstable with the stress of being in a hard relationship, so if she lashes out I wouldn't take it personal. Also, if she argues with you and defends him it's likely cause she loves him and doesn't want to confront the reality of the situation she's in. I wouldn't get angry at her, she could be hurting inside. Just my 2 cents.
