thanks for some of the comments.
anyway, in general if you ask the guys ard you. even if they are
tall, most would prefer petite and short girls. so u see, short
guys prefer short girls. tall guy oso, then tall zabor go jump
bridge?
i think it's my self esteem problem 
Not all guys want short girls.
And as everyone here has been saying..... 170cm is not that tall
to begin with. Heck.... a few girls taller than you posted their
comments in this thread.
I'll be blunt about this: if a lot of guys have been shying away
from you, then most likely it's not because of your height.
More likely, it's because of your lack of self-confidence.
