Idk if I like my engagement ring

Andy
My bf proposed on our 5th anniversary during Canada Day's Fireworks. It was the cutest thing ever. He told me he had a hard time picking the ring and it is the real deal because I deserve the best buuuuuut... I'm not sure I like it all that much. It's not ugly or anything, it's just not quite my style. He says he reads it in my face and that we could upgrade or change it next year since he paid insurance but I don't want to hurt his feelings being stupid and vain.. what do you girls think?
