I am feeling like I should be upset that my girlfriend got me nothing for Valentine's Day.
Oh dude, really? Why are you upset about that?
I gave her my heart and she gave me a stone
I know you're upset, but you shouldn't always expect someone to buy things for you. Love is all you should need.
I'm a man. Men need gifts, too.
You are a guy and that means you will spend more on your girlfriend than she does on you. Its a natural fact, and should be accepted. Once in awhile buy yourself a gift too.
