Am I being selfish?

My boyfriend bought me a $200 ring. It hasn’t come in the mail yet, but I saw the order receipt. I kind of don’t know how to react when he gives it to me because while I do appreciate the fact that he’s willing to spend that amount of money on me, I NEVER wear rings. I am stuck between if I think it’s a thoughtful gift or not. It’s sweet of him to buy me a ring and especially for that much, but the problem is the fact that he doesn’t pay attention or know me well enough to notice I don’t wear rings. I never wear any jewelry at all. I feel like it’s not a gift specifically for me, I feel like it’s a gift he could buy just any girl. Not that I’m not grateful, but I’ve been mentioning a north face that I’ve been thinking about buying that’s the same price. I don’t mean to be a bitch because I really DO appreciate the ring, but if he is going to spend $200 I would prefer it to be something I’m going to get use out of rather than sitting on my night stand. I think I’m going to just suck it up and pretend to be happy about the gift, but does anyone have an opinion about this?

Edit; it’s not a proposal ring. I’m 18.
