Does a crush last?

If a girl who i see regularly has a crush on me the same way i have on her but both of us are too shy and keep waiting for the perfect chance to talk will her crush fade.

I do plan on making a move next time i see her but im worried its too late now.

You live in a competitive environment.

Most women's attention is fleeting and social dynamics mean that other men will persue her.

You probably have few months before a man without your inhibitions captures her attention.
