Am I over reacting?

I sent the guy I’m talking to a birthday gift and card as a surprise, because he is over seas right now. I wrote in his birthday card some sweet things. He got it today and sent a picture of it letting me know he received it. Then told me how his friend saw it and asked about the nickname I wrote in it. That’s all. Then he changed the subject. Didn’t say thank you, didn’t say he liked it, didn’t say he was surprised or that it was sweet of me. Nothing. So when I asked do u like it? All he responded was, “I’ll use it next week to celebrate”. (It’s a shot glass) Then he changed the subject. And then I replied your welcome. And he just replied thank you... now he’s asking why I’m upset and I told him that I feel unappreciated and dumb for sending anything and he says that no the only dumb thing is that I’m mad because his reaction isn’t how I envisioned it would be..but he didn’t even HAVE a reaction or say anything about it other than that he got it. Am I over reacting? Idk to me it seems rude and ungrateful.
