wow chickan you do it the old fashioned way
first ask if she has a man, then say if she dont "im surprised you dont, have this glow about you" she probably will smile, dont say movies, or bowling, say can i take you out to dinner
When a girl knows you will spend more, in their head means they are worth more to you, after shes yours then be cheap and bring her to the dollar store, and 2 dollar theater and mcdonalds
pretty means more when you know her more and you can look her in the eyes and tell her in private while being close
