I would’ve said “I love it but it doesn’t match my engagement ring and I wanted to wear my engagement ring too even when married because I love it so much - is there any way we can get something that will match it better?”
Could you also not compromise and make it into a necklace instead and still get a ring you love? That way you wouldn’t have to get rid of it
Its okay for him to be butt hurt but as long as you’re super nice and gentle about it he should go with u to return it and find something more suiting. Its the thought that counts. Once he gets over being sad he didnt get it right the first time (and being excited to give you it and see your reaction) he will enjoy picking out the perfect one for you with you.
I can understand both of you in this situation. You don’t want it because it doesn’t suit your taste or match your other rings yet your husband is upset because I assume he took the time to find it or picked it for a reason perhaps? I think both of your feelings are valid however, his reaction could be better(maybe he’s just too upset at the moment to process his feelings)but also you’re the one who has to wear it and if you’re not happy then you’re not happy. If he is happy with his ring then you should also be happy with yours and I think having a gentle conversation with him after giving him the space he needs and explain it’s not against him, you’re delighted he wants to pick a ring for you but you want it to be the same colour or similar to your other rings. At the end of the day, both of you deserve to be happy with what you wear because you’ll also be wearing it for a very long time
