We met at the 18th birthday party of our friend. (I knew about her only on Facebook, but I never added her to friends or something, I just asked some of my friends about her, and everyone said that there are like 30 guys wanting to be with her but she had no boyfriend ever.) Anyways, she and two of her friends approached mine and friends table on birthday. We danced, laughed, talked, had fun generally. After the party we split up and I stayed with her for about 2 hours, we kissed and so...After that party, we met up only 2 times for about 3-4 hours.
We didn't see each other for about a week because she said she was busy. After 4 days I asked her again if she was free on Sunday (when I asked her it was Thursday) and she said that she will try her best. Day after ( Friday) we messaged and she said that she can not make it on Sunday. Later that day she called me and asked me if I could come that day (Friday) so we could have fun...which I couldn't because I already arranged something with friend of mine. On Sunday we broke up...this is something like what she said:"I have to talk to you. You see that I am busy lately and I never have time to see you, I don't want to do this to you anymore, my grades are really bad and I have to study a lot, It is a really bad situation, I don't know what to say..."
I don't know what to do, should I wait for her school to finish and try again or she just said in a nice way that she is not interested? (I know 100% is true from my female friends that she has 4 really bad grades that she has to fix and when they call her out, she is always busy). I'm the first guy she went out with...she called me back on that Friday to go out with me...I'm confused, a lot. Her school ends in 4 weeks.
