For my birthday, my spouse got me a nicer newer expensive version of a thing I already have. The one I have is older and dented but works just fine. I use it weekly. I never complain about it. I’ve never asked for a newer one. The one I have was given to me by my mother in law, whom I adore. It’s sentimental.
I don’t like new things. When they got me a 3d printer, it was the cheapest one and it was a kit and I had to build myself. I loved it. It’s perfect for me. I regularly buy things used or get things from Buy Nothing groups. I much prefer to repair old things in many ways. My car has over 100k miles. The one before did too. I don’t like new things.
We got into a huge argument because I want to return it. They are so upset with me that they left the house to calm down. Why am I the bad person? Why are they mad at me? I have a very clear tendency for old broken used things. Why am I obligated to like this new thing?
We literally established a rule early in our marriage. I’m not allowed to gift nerdy t shirts. They don’t like them. I love them. I thought they would like them but they do not. So they asked me to stop. This feels the same. I do not like new things. Why am I the bad guy for wanting to return the newer version of the thing I already have?
It’s not about the item whatever it is, it’s about your reaction to it. This was something your spouse got you to show you that they love you; they bought something they thought you would want and need because they see you using this item all the time. It doesn’t matter that they know you like using old things - for them the thing they got you is an expression of their love for you, and your reaction (lets return it, I don’t want it) is like rejecting their love and is insulting.
I don’t know how you said it to your spouse but the way you’ve described it here your reaction sounds like it was entirely factual and emotionless. It may not be what you’re saying but how you said it that is the issue. Did you acknowledge how kind and thoughtful the gift was? Did you acknowledge what it means to get a nice gift from your spouse before saying that actually it’s not something you’d use?
Instead of seeing it as a tit-for-tat exchange and the same as you gifting t-shirts, you need to understand that this was a personal gift from your spouse. You also need to acknowledge you’re difficult to get gifts for because you like old things. You’re not the bad guy for wanting to return the item, you’re likely the bad guy for how you’ve gone about it and hurting your spouses feelings in the process. It may be that you’re not an emotional person or have difficulty reading other people including your spouse - that’s fine but you may need to acknowledge that you’ve hurt their feelings even if you didn’t realise or mean to, and apologise - that may help a lot. It would also be helpful to tell them how your mother-in-laws gift has sentimental value and you didn’t want to replace it. It may still be that you end up returning the item - but it’s far less important that your relationship with your spouse.
To piggy back off this one, because I liked it, I’d like to zoom in on the spouse’s reaction. Yes, it’s an expression of their love. But also, if they’re the sort of person that feels gift-giving is important, then they probably struggle with you being hard to buy for, because they want to get you something, because that’s how they demonstrate love and attention.
So probably they’ve been watching you, and they noticed you spend a lot of time with this item, and they thought if they got you a new or fancy version it would make for a great gift. They finally found something they know you’ll like! They’ll watch you open it, you’ll light up, and thank them for their keen insight, attention, and creativity. The perfect gift.
Obviously it didn’t go down that way, but I think in addition to just “rejecting their love”, I imagine there’s also a huge factor that is just shock and disappointment. They had high expectations, they were excited for the reveal, and what they got was so much worse than what they expected they just don’t even know what to do with this energy. They may even be a little embarrassed, both that they got you a bad gift, and at their misplaced excitement.
It’s just an emotional letdown for them, I imagine. Now depending on their emotional maturity, they may just need to collect themselves, realize this whole thing was their fault for getting their hopes up even though you’ve told them you’re not interested. They’ll realize you have good reasons to want to keep the old one, and that they overlooked the importance of it. And if they don’t have that level of mindfulness, then they may calm down, but they’ll still blame you fully.
Anyway, just wanted to point out what I expect the source of the “outsized”-feeling reaction might be. Acute, sudden onset, disappointment.
