so my girlfriend and i have been dating for a while, and she always wants to do 'stuff'. like going out to eat, to the movies, renting movies, etc. so i have been taking her out and stuff, but its getting to be pretty expensive. she comes from a bit of money, and i dont think she really has a very good concept of money. so how can i let her know that i still love her, but i cant be dropping tons of money all the time on us doing things?
