Hmmm.... well, I duno if I shld say some words but here goes.
Sorry if they sound abit to your disliking.
I think that there are other ways to find out if a girl is attached
like asking a fren or jsut asking her in a joking manner whether
she is attached. U can also hint her instead of opening confessing
to her. Mayb she did not get your hints?Of cos, if she lie to u or
duno how to take hints, then it dun work la. But i think confession
is the last thing u shld do.
It shld come after all the things that needs to be done is done.
Like knowing her well, know that at least she has a liking for u,
knowing she is single of cos, etc etc.
I think your reason for confession is abit out of place. I
understand why u are so eager but at the same time while trying to
get the info, u could get to know her better so that u can get info
easier isnt it?
Anyway, good luck for tonite.
