Input: So 13 months ago I got with my now fiance. We jumped into a very serious relationship VERY quickly. We went on one date and then basically just moved in together immediately. ( I KNOW...I know..)
I was completely infatuated at first and thought I was in love. She had just quit her job and was unemployed and was suffering from some serious depression. She didn't get out of bed for days at a time. I really liked her and thought I could "save" her. He 13 year old son got tired of her not getting up and not being involved in life and called CPS. They took the kids temporarily and gave her a hearing. I tried telling her that she needed a lawyer and she didn't listen. Long story short, she lost full custody of her kids and now only sees them part time. 
This made her depression even worse. In the 13 months we've been together she has had 4 jobs. All of which she would call off constantly and hasn't last in one for more than two months. She has been at her current job at Cincinnati Children's hospital for less than two months and has already called off twice.
She doesn't take care of herself. She doesn't clean up after herself. She constantly pretends she is sick to get out of EVERYTHING. She is basically useless. I'm sorry to use that term, but it's the truth. Hell, she only showers two times a week MAX. Her family completely turned their backs on her. None of them even speak to her. She has literally NO ONE other than me. 
I made a lot of promises early on. I thought I was in love with her, and think I really was. At least with the person I thought she was. We don't talk, we don't go out, or laugh together. We just coexist in a house together. She literally won't give me a reason to stay. I've grown so far away from her that I am actually starting to despise her as a person. She is kind hearted, but I just can't take much more. She blames it all on me. Tells me that I make her feel worthless. But I have done nothing but try to help her. 
If I leave her, I am afraid of what she will do. I am afraid she will slip even further. She won't be able to care for herself. The part of me that still loves parts of her is just so torn. I am all she really has. But I am growing to hate her. 
WIBTA if I leave her completely alone in life?
