I do the very expensive flowers bit every year by an award-winning flower shop. . . and I only do that because my wife really LOVES flowers and flower arrangements, she really appreciates it and makes me feel that I DID THE RIGHT THING. Also, no one else at her office gets flowers even vaguely resembling the flowers she gets, and that doesn't hurt my standing with her either! It puts the pinch on my finances every February, but it's really honestly appreciated and I always do it. So guess no answers from me. If your wife really has been enjoying the flowers, you may want to continue with that tradition. .. . If not, lots of options.
We often also go to one of our favorite restaurants one evening either before, after or on Valentine's Day, usually the Clay Pit (fabulous Indian food) or Fonda San Miguel (fantastic Mexican food).
