My only advice is to choose your path wisely and not regret it
later on in life, be it waiting or forgetting about the girl.
I had similar probelms a while back, but think about it, if she
really breaks off with her current significant half to be with you,
what makes you think she might not do it again in future when she's
with you?
I'm not implying anything bad, but respect her choices and make
your own choice based on the current situation.
