Yeah,
actually it's quite common. I know of people whom ALMOST ONLY step
in to woo girls, when she broke up with his bf. And if she is
attached, they will hang around like a leech, until they broke off
and dive in like a vulture. An irritating thingy is that these
causal friends of mine ALWAYS claim 'chi qing', talk about fate and
all sort of rubbish. Interestingly, they almost always pick girls
with problematic relationship with their bf. I am not including the
fact that they give the-people-involved an aura that he is a good
person. When they see through the 'real him' - every single one
broke off with him.
I seen enough repetition of his style that I got so
disgusted.
To me, personally, it depends on situation, on how it ended, the
cause, source and outcome.
MC: Sometimes, this is the only time some people could have a
chance at their long awaited crush. You see, not everyone see the
perfect picture and rarely does the perfect scenario of chasing
someone appear. Some people only have that ONE chance at it and if
they miss it, it is gone.
More like secure it first, anything else, talk later. 
Cheers
