For the gift that really says, "I love you", go for a furnace. That's what we did. Our furnace was giving out, leaving our house in the low 40's in the morning. This does not make for a happy situation. We started looking at furnaces, and the folks we went with brought over a bunch of space heaters. This was fine, except we were heading out of town for a romantic stay in a bed and breakfast in Georgetown, Colorado, which may or may not have been our actual Valentine's Day present. I didn't want to leave the heaters running for fear of burning down the house. Jen didn't want to turn them off for fear of the pipes freezing. Fortunately Jen's parents came through and volunteered to stay the night at our house to make sure neither catastrophe occurred.
We had a great time at our B&B, and on Valentine's Day proper I got Jen some exotic chocolates (salted caramel with rosemary is awesome) and she got me this awesome shelf arrangement for my dunnies and other art toys. We threw together a pretty simple but excellent pasta dinner with some decadent cheese bread. And it was good. I love my amazing wife! It was 3 years ago that I proposed to her on Valentine's Day, and my life has been so much richer since. And now, with a new furnace, it can be warmer too.
