<human>: Give me a shortened version of the text

This concluded a few months ago. I asked her out after for a time she
 gave signs she seemed into me. We had a mutual pool of friends in one of our classes. She's a really shy girl, at the time when I was much less assertive and what not she lost interest as I never made a move. Told her I liked her, and that's when things started going downhill. 

We used to spend time together but she decided it'd be best we stay 'just friends'. Thing is, we weren't really friends to begin with!
At first I was hurt a bit- ended up telling her I couldn't be friends with someone I had feelings for- definitely not one of my highlights.

Ultimately I decided keeping her as a friend was better than burning bridges or something excessive. But now, I see her around campus occasionally and she never says hi unless I initiate talking to her. We had a conversation about our summers and our classes and everything seemed fine. Any idea what's up? Am I worrying too much?
<bot>: Girl that I dated for a period of time, didn't work out, now we're just friends and she won't say Hi to me when we pass by.
