Roommate is Jobless for Almost a Year and Won't Leave

My roommate (ex-girlfriend) has been unemployed for almost a year now and refuses to leave to find other housing. We don't talk about her job hunt because we hardly communicate anymore, all I know is that she claims that she hates to live with me. Her parents will not help her out and she has no friends in the area that can help her out either (because they all live in studio apartments). I pay all the rent and have like 6 months left on this lease, she won't let me off the lease either. I don't know if there is anything I can do to get myself out of this situation.
