Don't be sad pal, such things are pretty normal.
All you have to do now is: -
1) Let her settle her feelings first.
2) Continue to keep in contact with her, but cut down on meeting
her regularly or frequently. Best if you two can chat over the
phone once in a while.
3) Go out, take some fresh air, and make more friends. In that way,
you'll widen your social circle (including women too). Don't have
to stick to the same girl all the time.
4) Repeat the above. Hehehe... 
Oh, one more thing. If she gives you the excuse like not ready to
have a relationship or so, most of the time, it clearly means that
she's not attracted to you in the first place. So, I would advice
you to stay out of her life and move on.
You may want to proceed with the 3 steps I've highlighted for you..
it's perfectly okay. Just that you do it at your own risk of
breaking your own heart. The choice is yours.
All the best of hope!
yours sincerely,
S.H.I.N.
