I would go w/ a card and maybe flowers that you give her instead of having them delivered. I got a very non-mushy card for H. I won't give it to him unless he gives me one. I also have a box of candy that he will like, just incase. I will follow his lead.
My H is seeing his C tomorrow also. I don't think he realized it was v-day when he made the appt. I also don't think the day means a thing to him. It has never been a big day for us, although I do remember where he took me to dinner the first year we were married. It is 1000 miles from where we live so I don't think we will be going there tomorrow, not that we will go anywhere.
