It's a girl I've known for about a year now but didn't really start chatting with her for about a month.
Back story:
A chick friend of mine (who we'll call girl A) introduced me to her friend (who we'll call girl B) about a year ago. I liked girl B almost from the start. However, I didn't like her too much and I was too nervous to do anything (I kept my cool at the time, but had only that one convo with her for almost a year now). Anyways, after girl B left, I told girl A that girl B was really hot. A few months later, girl A told me that she told her friend (girl B) what I said, and that girl B thought I was cute. Why at that point I didn't try to hit on her is passed me. Anyways, the semester for college was ending soon and I wanted to do something, so I started talking with her A LOT more and trying to get closer. So far, I asked her out once to a cafe and she shot me down saying that she was swamped with homework (which is true, she was complaining about it for a while, was even working on it while I was there with her doing my own homework, but I gave it a shot anyways). I asked her out again on the last day of school to a thing my friend was doing at his university. She said she was busy again going to another city (which could be true, a lot of people here go to that nearby city for a few days). She however did invite me to a party later that day that she was invited to. Unfortunately, I had already made plans, so I couldn't go. Forgot to get her number there tho.
Recently (4 days ago), during exam period (no classes, just scheduled tests), I saw her in the school after I finished my test (well, she saw me and called me over). She said that she was going to a nearby cafe to hang out with one of her closest friends and asked if I wanted to go with her (well, in the same direction, she knows I live somewhat close to her, which is also close to the cafe). I said sure and on the bus ride there, I asked her for her number and said we should hang out some time. She at first said no. I felt really awkward and she very clearly saw that and said she's sorry and she's not trying to reject me or anything. She said if I wanted to hang out with her, I could use Facebook. I told her it's too awkward to ask someone to hang out on Facebook. To which she replied that it would be fine if I did on Facebook and that she doesn't give out her number to people she already has on Facebook since she doesn't text or call much (which is a lie, I've hung out with her in school, she does those quite a bit). Anyways, she apologized again and said she would give me her number. I told her if she didn't want to, then she didn't have to. She said, no, it's ok, then gave me her number. I still felt really bad not only because she said no but I think I just kinda forced her into giving me her number, which I really don't like doing. So I left to my buddies place sine we planned to go to the theaters together.
Anyways, what should I think and do now?
