Do you think she likes me? What should I do?

[Fidelity]

There's this girl that I met 5 months ago, and were friends, but I like her more than that. I've actually been in love with this girl since last year, but I haven't talked to her till now. We always talk and our relationship began to develop. I started walking her to classes in school, and talking to her all the time. I followed her on Twitter and she automatically tweeted me with excitement. The next day she said she would come watch me at one of my soccer games when the season starts. I was super happy! I wanted to see if she really did like me, so I experimented. One day I decided not to talk to her at all. She was in the cafeteria, so I said hey to one girl that was sitting beside her. She looked at me with jealousy, it was like "Umm, why did you just say hey to her?" The next day I wanted to see if she'd walk with me if she saw me. She did! She did several times too. I was super happy, so I wanted to take it to the next level. I wanted her number. In math class, her best friend, who was sitting behind her, was like "hey want my number?" I was like "Why?" and then she was like "Never mind" and I was like "No tell me" she wouldn't give it to me. So I was like "Hey what's her number" to the girl that I liked, and she was like "My number or hers?" and then I was like "Give me both." She accepted. But then her best friend was like "Okay, i'll give you my number." As I was writing her number down, the teacher told me to put my phone up. So I did, and I lost her best friend's number. So then her best friend was like "you're not getting it again." And I turned to the girl that I liked and was like "What's your number?" and she was like "Why?" and I was like "So I can get yours and hers" and then she was like "Then you don't need it." I was confused. She then talked to me normally like before, and smiled and everything. But I don't know. Why did she not give me her number? I mean does she like me? I do act weird in front of her, and i'm weird in class. But i'm funny. Please help!
