Does the fact that she refused to be my wing women might show that she likes me and it's painful for her?

She tested me and I decided to test her back and see won me over.Now how can I win her ove and did she or does she like me?.Last time we talked I asked her to be my wing women and she said I am flattered but no and I asked her why and she said because I have a lot of guys in my life and I don't want to have the pressure.I now decided I want her and no other girl and don't want her to be my wing woman but want her to be my girlfriend and the wing woman was an excuse. Could it be that she likes me and does not want to train me to be with other girls but her.That would make sense because why would you be a wing man/woman for a person you want for yourself.I thought she is alright at first and did not really like her but that is how it started. We are in the same college cl and we are both in our early 20s. So our cl was in the other building this day rather in the same place we always meet. SO she seen me in the parking lot and she said our cl is over there and I should hop with her in the car. So we talked about jobs and that she has 5 jobs. And one of them is modeling t-shirts. I asked her if there is any job openings and she said I will inform you when there is. Then in the library when she was on the computer I asked if I can add her on facebook and she said sure. Then she said she has a roller derby game coming up and that I should come . Then I asked her where it is then she said where and I asked her if she can send it by facebook message and she said she will then I sent her a message asking her where and she did not respond to the message but posted the even on her wall. I kept asking her about roller derby and she said let me show you moves since you are use to physical contact and she touched me by pushing against my knees and showed me how she knocks big girls to the ground my leverage and then did a second move by hitting my body and it did not work and she said I am solid. She is average height but slim and small and I am tall and big. Her facebook profile says single but her looking for says friendship. I asked her if she is seeing someone and she said yes sorry. But I don't by it I am sure she is single but just telling me that as an excuse to get out of dating me. She said I am sure another girl will be happy to be your wing woman and you will find someone. I felt she was checking me out and she is the only girl that volunteers to act with me in our acting cl. She said that our roller derby team has hot chicks and guy fans don't realize this but they get to date some and I said hot like you and she said yes like me and waved and flapped her arms at me in the air and smiled and stared at me.I liked her confidence and strong will and I decided I want to date her and know other girl at this point and I am starting to fall for her What can I do to win her over?
