Hi c2on2, I don't think she doesn't like you and as what
cutepixie said, she would have rejected you on the spot if she
doesn't.
There could be something there's hindering her, maybe an unhappy
previous relationship, maybe haven't got over her ex, maybe not
ready for a new relationship, many many possibilities. Did you find
out all these before you actually confessed to her?
Since you have already done what you did, don't worry about the
outcome. Continue keeping in touch with her but DO NOT BROACH ON
THE TOPIC on starting a relationship. Keep everything as for normal
and wait for her to bring up the topic with you.
Good luck!
