I got nothin'.

Honestly, the last relationship I was in ended late '06, and I've almost never been in a relationship through (coincidentally) Valentine's Day. That's not for lack of interest or high standards on my part, but for lack of interest from good women, lack of reciprocal interest by the woman I had interest in, or lack of testicular fortitude on my part. (Basically, I had a chance, but didn't know because I didn't have the balls to pursue further ... this happened once again less than a month ago, and the lady I was trying to start a relationship with ended up doing the same with somebody else because she got tired of waiting. Why can I face terrorists and gunshots and mortars and RPGs and IEDs for more than two years in Iraq, but I don't have the courage to confront a good-looking girl?)

Anyway. The last relationship I was in through Valentine's Day (which was in high school, mind you, in '01), I got my girlfriend a necklace with a heart and a rose on it. Not very expensive, since I didn't have much to spend, but it definitely worked. I had brought her roses on multiple occasions, so there was kind of a point to the necklace -- that's the trick, you can't just go out and get anything, because unless you're spending quite a bit on something extravagant, she'll wonder why you got her what you got her. There's always the sure bet -- teddy bears, chocolate, stuff like that -- but, in my opinion anyway, the best gifts are (as has been said) those that come from the heart. (Even though some teddy bears are good for this.) Get something for her based on how big your heart is for her, not how big your wallet is.
