what should i get my girlfriend for valentines day?

If u live together, the night before valentines day, while she is asleep, put like hints and gifts about where u are, like have her walk around town until she finds u. And when she does, she will be walking right into a romantic date ( 4 u and her) and u can even propose if u want, its what my bro did(:

Nothin

Box of chocolates and a rose. Traditional always works.

You know her better than i do.
