Should I allow my female friend to continue living with me?

I have a female friend who was down on her luck so I invited her to stay with me for a while. Since that time she has tried to help out around the apartment by cooking and cleaning and other things from time to time. She also gives me a few dollars from time to time because she Isnt working steadily right now. In many ways she has been a big help. But the problem comes in with her attitude. I am African American and she is too and one day she was on the phone in front of me talking about how terrible black men are and saying how much better white men are while she is sitting on my couch, living in my apartment, and eating my food. She also complains constantly about my bachelor lifestyle and has even started telling me what I can and cannot do. She feels free to come and go when she pleases and help out when she pleases. She constantly complains about getting her own apartment as soon as possible but even though she is a productive person she spends most of her time complianing instead of searching for a job. So far she has only applied to one place (SUBWAY) and thinks that will be the answer to all her problems. She works independently in the fashion industry but its obviously not paying off. This are becoming awkward and frankly I'm begginning to feel that I need my space back but i know how roomate situations can be (even though I don't consider her a roomate but rather a guest). I think she thinks she's a roomate instead of just a guest. Sometimes I get the feeling she's complaining to her friends about me even though I've gone out of my way to help her. I don't want to jump the gun and I do want to maintain her friendship if possible. What do you think I should do?
