Let me ask everyone this, would it be different if the OP bought her something else that he knows she doesnt like if it wasnt flowers. I think everyone gets caught up in the flowers are a lovely gift where to some, not so much.And esp on Vday a bouguet of flowers can cost as much as a piece of jewelry or a purse.
Like I will use DH as an example, his mom LOVES flowers, jewelry and designer purses. His WIFE likes flowers (not love) likes minimal jewelry, and really does not get designer purses. Some are nice but I dont need a designer purse, I need a purse I think is nice and functional, if it is designer too then cool but it doesnt have to be. His WIFE likes the gift of time, or a massage, or pedicure.
So for years DH would walk into some store the day of the holiday (or Christmas eve) and buy me one of these things bc it required no thought, he just pointd to the most expensive purse ($300 somtimes

) and call it a day. No thought into what his WIFE would like. Then he would get mad that I wouldnt use the purse or if he thought to put a gift receipt in I would return it. He couldnt understand why I didnt like a purse that had Dooney and Burke spalshed all over it (as I am sure many women reading this thread dont understand me either

) bc he mom would have loved it. She buys them for herself.
To me he was buying me what he was trained to buy not listening or knowing who I am. Has he gotten better, a little, have I learned not to get worked up, sometimes, but I still get frustrated that he has now spent our money on something that will sit in a closet. He may be using his love language or whatever but he certainly hasnt listened to mine. That hurts and it is frustrating bc we dont have that kind of money to blow.
Two Chirstmases ago, I needed a new evening type purse so I told him that and told him have fun. I think he was so relivied. He went and got me D&B black small purse, it is subtle (not screaming D&B) and I love it. But this took a long time to get there.
I also think this all goes back to how we were raised. DH was taught no practical gifts allowed by his mom. My parents didnt "listen" when I made a wish list at Christmas and bought me nothing on my list yet asked me to make one

So I think couples also bring their experiences to a relationship and if they are very different then this can cause some bumps in the road.
