Moo I have been in your situation many, many times over the years. Sometimes I have kept things which are not to my taste, because my partner chose them with love.
However I remember an expensive bracelet that he bought me one Christmas from a jewellery store that had loads of lovely things. I really didn’t like the bracelet and given the cost, decided to be honest and explain.
We went back to the jewellers together and exchanged the bracelet for one I much preferred. That was in 1986 and I still love and wear the replacement bracelet.
I think the thing that made the difference was the cost, it would have been sad to have the expensive, unloved bracelet, languishing in its box. I don’t remember my partner being particularly upset at the time, I think he was happy that I ended up with something I loved and wore a lot.
