Am I being too sensitive?

I worked very hard to pick out some nice things for my boyfriend for Christmas. I got him 2 pairs of jeans, a nice jacket, a shirt, a hat, and a 55 inch roku TV. He asked for jeans and a TV but he never thought I would actually get a tv because it's a big gift. So that was the big surprise. I researched the TV and picked out a nice one that wasn't crazy expensive but not cheap. And then I got the hat because he loves hats and is always wearing a hat wherever he goes.

Anyway the jeans didn't fit. So of course I said we will take it back and you can get what fits and what you want. Then he asked me how much the hat was and he said oh we can take that back and I could probably get 2 for that price. I was like wait a minute if it doesn't fit or you don't like it it's one thing but to take it back to get something else just to do so, then I don't like that. He didn't understand and said I shouldn't be upset. Then today he said he's looking at tvs and says he might want to take it back and get a different one even though this TV is nice. He can get a better one now because he can just pay the difference (even though if he bought the TV himself he would probably be in the same price range as this TV).

So now I'm bothered because it's like he wants to exchange just about everything and I spent so much time picking out things just for him. I was thoughtful about everything. And I did a lot of research about the TV so it wasn't like I just picked anything out. Am I just being too sensitive?
