what would you do, if anything?
A friend of many years is married to a man who (I don't think) is physically abusive, but definitely EA. He makes no attempt to disguise his behaviour in front of house guests (ie me and others), and constantly puts her down, taunts her and disregards her. More than that, he actually seems to go out of his way to mess her around and change his plans at the last minute, etc, so he can tell her she's stupid for not keeping up.
She has clearly changed over the last few years (since marrying him). She doesn't really go out anymore apart from shopping for the family. She used to have an interest in her appearance but doesn't do anything for herself now.
I am worried about her, but don't know what to do. The problem is that she has never said anything about it, at all. A few months ago her H shouted abuse at her in front of me. I lost my temper and shouted at him that he was out of order. She stepped in and asked me to 'drop it please'. I then didn't see her for a few weeks (she avoided me) and when I finally got to see her again, she made it clear she didn't want to talk about it. He has kept out of my way since. But I feel guilty and a bit responsible that I know she's unhappy and I'm not doing anything to help.
What should I do, if anything? I don't know what the rules are in this kind of situation and it is constantly playing on my mind
