My fiance and I decided not to celebrate it b/c we are saving for our wedding and don't need to spend unecessarily right now. That said, I've spent lots of Valentine's Days with ex-boyfriends but one of my best V-Day memories was when my best friend and I went to a dinner/concert that was actually marketed for couples. But the concert was one of my favorite artists, and I dragged her along - we had an awesome dinner and saw a great show. It was a wonderful night!
