How many times should a guy try for a girl?

Seems like girls want the guy to make the first move. Some want them to try again even after rejection. So how many times should he try?

Thank you everyone for your answers. As most of you advised I stopped trying after getting turned down. But the confusing part is I learned a while later she had a crush on me.

Ag that point I should still stay friends even if she had a crush and gets jelly if I see someone else?
