Looking for some advice on how to deal with this situation. A close friend has a very volatile relationship with her husband. They've always argued a lot (been together about 15 years) and been on and off until they had children. She struggles through life and has mental health problems that she hasn't addressed. I found out from her recently that she hits her husband when they argue but he doesn't retaliate. Last night she text me that they had a physical fight (I don't know if it was two way) in front of their children.
She's always been a very good friend to me and is always kind and caring to other people. I want to help her but I find this behaviour shocking and unacceptable. She wants me to make her feel better, that's it's normal and she's not in the wrong but I can't do that. I know that he pushes her to her limits emotionally and suspect he gaslights her. I just don't know how to help her and I'm really worried about her children witnessing violence like this. Any advice?
