Well...If I were you, I would have given her time....You are neither her boyfriend nor her brother to pay for her...and if she has this expectation in your friendship, then honesty that's not a friendship at all....
You got to be relaxed and let time solve your problem...Trust me, she will get back to you....If you two were good friends and spend so much time together then she will miss you as well....
Yes...this is a time to find your interests.....and you get dettached from her....attachments are not good, it will bring suffering....
take care and be paitent
