<human>: Could you distill the essence of the text into 1-3 sentences?

So she walks up behind me to talk, which isn't the first time we've talked or the first time she has came up to me. Walked a little bit, talked a little bit, at the end I asked if she wanted to hangout, and I'm sure she could tell I was nervous, but she said she might be busy with work so she asked for my number and said she would text me. And note I did not get her number, as this would be the last time I would most likely ever see her again unless she contacts me.

This was on Wednesday, and am expecting for her to text me on either Friday or Saturday. 

I know she could have just been nice to ask for my number and kind of reject me in a nice way, but then she could of gave me hers (forgot to ask, thought giving her mine would be enough, but has its pros and cons).
<bot>: If she does text me and say she's free to go or want's to make plans for another day, would it at the very least mean she's interested?
