I met this girl today at school. I was walking into the library and she was walking out. I struck up a conversation with her and it went well. A couple times I was ready to let the conversation die and she kept it going. Gave me several IOIs as well. When she was about to go (she had class in a few minutes), I debated whether to ask for her number, but decided against it. It was just a gut decision, asking for her number didn't seem like quite the right decision at the time, and she seemed to be of the rather conservative type. But now I'm second guessing my decision to hold off.

I'm sure I'll see her again. I've seen her all semester around campus but never got around to talking to her probably because I'm generally zoned out and thinking when I'm walking somewhere. Next time I'll ask her if she wants to get lunch or something and if she says yes then get her number. But I wanted to know if I blew my oppurtunity, if I should have gone for the number close right away. Think I might have?

no reason here to think you blew your opportunity, just tell her about some party youre going to next time you see her and get her number then
