Does she or dosent she?? im desperatre for help..?

So im at a wedding and i see this cute girl who smiles and makes eye contact with me. At the reception I see her and approach her. I ask her do you know the bride or the groom because I know them both and I dont think I have ever met you.. She said I know the bride I go to school with her. She says my name is so and so and puts out her hand and says nice to meet you. I introduce myself as well. We talk for awhile and she asks me if I know the bride or the groom and I tell her. I then ask her where she went to school, and if she had a boyfriend. She told me her school and said no I havent really had time for a bf while she was in school. Then she asked me where I lived, when I told her she said she lived close to me. So our convo went on and on, she told me about her job, and school and that she sung at weddings. Then while she was taking pictures she moved one seat down right next to me because she said she couldnt see from the other chair which was right beside of her. As she was leaving I asked her if she wanted to go out sometime and she said sure, I will get your number off so and so (the bride) and call you. Its been three days and she hasnt called. Do you think shes interested, and if so should I get her number and call her?
