Tired of worrying

So I met this girl a couple months ago things are really great between us we are basically dating but she doesn't like tittles because she feels trapped if there is a title that and because I don't have my GED(I go for the test in 2 days) or a job I was working 2 seasonal jobs but they just ended and I mean its not like I haven't supported her financially I pay for everything. But her ex still lives with her at her parents house but they sleep in the same bed it drives me crazy I mean he does nothing all day except play video games he had a great job but was fired for never showing up. He got another job and lost it because he never showed up. He gets another job has it for a week and loses it because guess what he never showed up. She gets upset at me sometimes because I don't like the fact that they still sleep in the same bed I mean does that really make me such a horrible person? I know they aren't having sex but she tells me all the time about how he loves to cuddle with her oh and that he's still in love with her and want another chance I mean really and then she doesn't understand why I don't like him really? I don't want her to kick him out just make him sleep somewhere else she keeps talking about how he was going to start sleeping in the den but that's been for the past month that she talks about it. Then it was he was getting kicked out on January 2 but she was going to sneak him in if he couldn't find somewhere else to stay then one of her other friends said he could possibly stay with him but he was allowed to stay with her so she told her friend that he was staying with her. Its driving me crazy that she keeps him around but then comes to me and complains about how much she doesn't like him I mean if she doesn't like him so much wouldn't she have let him stay with her friend? I just feel like that if he some how turned his life around and got a job got and his GED she would leave me and go back to him because it seems she just wants somebody who has a job and an education. How crazy am I for thinking these things?

Not remotely crazy. This should be a dealbreaker. You cannot continue putting up with this.

Get rid of her...she wants her cake and eat it too.
