Valentines Day is what you choose to make of it. If you feel like you want to completely focus on your husband on that day, go for it!
If you feel obligated to do something that someone else expects you to do, change that by changing how you think and react to this kind of thing, Learn to handle it in a way that works better for you. Your Valentines Day activities should be something that is joyful for You. Do what you truly enjoy and wish to do, regardless of what anyone else does.
"We" don't need to "take back" anything for you to make a change in your life. That is something you need to do for yourself.
I don't want the same thing you want. I like to send Valentines and gifts to my friends, sister, mother, father, etc. I use the day to celebrate love of all kinds, not just romantic. This is what brings joy to me.
My kids are teenagers. They are years past the age of classroom valentine parties and such. Even though they are both taller than me and have deep manly voices, they are still kids on the inside. This morning they each found a special candy treat waiting for them. Seeing their eyes light up and the grins on their faces is never going to be a bad thing.
Added: I decorate the house a little too. Heart spinners hanging from the celing, decals on the window, etc. You know those mini garden flags? I use them as curtains for the small window of my front door. I have a Valentine one hanging there now.
