He didn’t even acknowledge what I did

[Rudetude]

So inspired by a thread I’ve read just now. My boyfriend has been having a hard time recently. He’s always treated me well so I decided to buy something he wanted for ages and planned a weekend for us to get away.

Booked dinner, paid for all drinks because he deserves a treat. He was really happy with it, I did say I wanted to get the upgraded version of his gift but he said it’s fine you paid for everything. We left each other this morning, he didn’t say thank you whilst we were there. Since he’s left me we haven’t spoken, I presumed he would text to say thank you or even just acknowledge it. I don’t know if I sound entitled but I feel a bit sad that I went to so much effort. I don’t want to text him to say anything but surely that’s rude

How did you know he was really happy with what you did for him? How did he show his happiness? Was that, perhaps, his thanks, his appreciation?

If I were you, I would do my favourite trick and ask him what the best bit was, and why. Let him think and then tell you.

You say he was really happy, so clearly he liked it, but didn't actually say Thank You?

It's hard to say without knowing more about him. Could be one of several reasons -
He might think he has said thank you
He might be planning a nice way of saying thank you
He might have enjoyed it but feel self concious that you paid for everything, and didn't enjoy feeling like a 'charity case' (of course that's now how you meant it, but some people can get touchy about that)
He might prefer it when he's the one doing the treating and doesn't like feeling like he owes you
He might be a rude, ungrateful person

Based on what you know of him, which of these is most likely?
