When a girl replies a short reply, it means you either have no
chance or she is busy or something similar. pwnz0r is right on
making the call though. So, a continual act of sending and
receiving SMS from one party indicates her interest in you even
though in short replies.
However, as a gentleman, you should not exploit her vulnerabilities
of her recent break up with her boyfriend. Love must be crystal
clear, not shrouded in the elements of darkness, conspiracy,
exploitation or manipulation.
Anyway, no chance already. So, take it as a valuable lesson for
your true love.
