Why do some guys wait for women to make the first move?

I really like this Asian guy but I feel like I have to initiate things first. I've always been told that men should pursue women, but now they say it's OK for women to go for what they want. I feel that if a guy likes you they will let you know. I'm not sure if it's

a cultural thing. I feel torn but don't want to miss out on a good thing.
