I was in the exact same situation as you are, perhaps even
slightly worse. Though there are many advices saying true 'love' is
worth waiting for, my advice is, if she is not keen, dont wait.
Unless she gave a very direct positive answer that she needs time,
and hope you wait for her, then do so. If not, dont waste your
time.
I waited for this girl for 2 years, and just 1 day she comes and
tell me she has already someone in mind. Once you hear that, i will
guarantee that your heart will sink like there is no bottom. Its a
gamble, and a really risky one. There is no 'confirm-chop' that
after so long, her heart is still with you, even more so when its
not be stable yet.
And its not up to you to 'do it or not'. The holding hand is
still hers. 2.5 years is neither long or short. Unless you are so
into her that you can never forget about her, i would say just move
on. Uni is the time to study too, dont get so troubled over such
stuff.
u r right bro. exam is just ard the corner. i better be
concentrating on my books instead of this kinda trivia stuff.
