You maybe hoped for more than she was prepared to give at her present time,and she detected it and got the jitters,not surprising really,,let things cool down for a while,drop her an email once a month with a polite how are you,hope you are well,but dont suggest a meet or expect a reply.
She will hopefully contact you in due course,but be prepared to be just friends.
Or you could try F#*k buddies!! :wink:
