hey bro,
doko and the rest already made it very clear. if she cant give u an
answer, means that she dunno how to reject u and her heart still
has him. do u want a girl wif her heart on others? i tried, but
failed. not possible already.
move on, tell her all the nasty words that how she treat u, make
her hate u if u cant hate her. really, move on bro.. i wouldnt want
u to treat the new gal as a sub, but u can try to love
again..
me and you, we're of same fate, spare tyres, admit it.
we cant control other ppl's action. everyone has to answer for
their own. find urself, get up again.
time heals, scars will be left, yes. but its a learning process, it
will remind u. ur next r/s will be better 
jack
