Friends Dangerous Abusive Relationship - What Should She Do?

Friends dangerous abusive relationship. What should she do? She sweet, she's kind, she's a good person, I love her and I want to help her. She's married to someone who is really mean to her. He says the most horrific things to her. He's abusive to her. She wants to leave but isn't working and can't support herself on her own right now. She is no stranger to the abuse as she has been with him for years and he's been like this for a long time. He's insulting, threatening, controlling, behavior is volitile and he's manipulative. He has some serious issues and isn't medicated for them because you know, he doesn't have issues, right? There must be steps to get out successfully and away from a crazy ass man like that, right? So what is the 1st step or steps? She has an issue with even being an abused person. So much shame she feels talking out loud about this issue. She knows she's not alone that there are others that have and/or are experiencing the very same, but still it's difficult and shameful. I see her as strong, fierce, opinonated and strong willed so it's truly difficult to imagine that she would put up with a man that would treat her so badly and for so so long. She's struggling. She's depressed, sad, yet she laughs at the things that make her so sad that could make her cry. She's hopeful for tomorrow and the day when she can stand on her own two feet without him around anymore. She has become desensitized and ironhearted in danger.
