I have been living for seven years with a man who took advantage of me financially. I paid the rent and utilities on my own for well over six years until his social security was granted. A few months later he decided it would be better for us to live apart. I'm all for it. It was impossible for me to get him to leave before, because he was bigger than me, stronger, scarier, emotionally and verbally abusive. I finally decided there was nothing I could do but wait it out. But you don't have to do that... and don't worry about what she'll do to survive. Once it is clear that she needs to support herself, she'll find a way even if it involves living in a homeless shelter for a few months. You are not responsible for her well-being. She is. Don't be co-dependent about this if the relationship is not making you happy.
