<human>: As the title says, how do pursue this girl that I think is possibly interested in me? I have had one real relationship that lasted a year and a half but I never did the whole "dating scene" because we were best friends before we ever started going out. I don't want to screw anything up with this new girl.

She is in one of my classes that only meets one day out of the week. We were paired up by the professor to do an easy group assignment. I talked with her and I can tell she seems like a girl I would like to be in a relationship with. 

I walked and talked with her on her way to her bus. The next week we had to meet somewhere and she was already there. I went to talk to her and she seemed so happy that I talked to her. The next week I walked her to the bus again and before I told her bye I asked her if I could get her number. She seemed relieved I asked and said "yeahhhh, of course!" I texted her a couple days after getting it but she never replied (I only sent one & didn't blow up her phone or anything). The next time I saw her in class, I didn't bring it up. When we had to present the group project, the first thing she told me that day was that her phone stopped working Thursday and didn't work the whole weekend for me, mom and others and she had to go to the store to get it fixed. Could she possibly be interested and if so, what should I do?

Can you give me the gist of the text in a nutshell?
<bot>: I met a girl in class that I think is interested in me, but I'm not sure what to do now so I don't screw up my chance with her.
