This would be a romantic gesture because it would show that you remember things that most people are accused of forgetting. If you enjoy reading and like poetry, add that to your quiet evening in front of the fire. Take turns reading out loud to each other. It may be just what the evening needs to turn into romance. Another great gift idea for her is a full day of beauty at her favorite salon.
Some hair salons offer great packages that include massages, facials, manicures, etc.
You can purchase the package and put the certificate in a card. A day of relaxation may be very much appreciated. Gift certificates, although thought by some to be an easy way out, are actually a good gift. If he or she has a favorite store, get a gift certificate from there. It will give that person a chance to go out shopping for themselves and that is always fun.
