Do papas who can’t say thank you to women think that, because they’re giving them money, they don’t need to show any gratitude?

Even when he changed our date because it was convenient for him, he never thanked me or apologized—he would just send some weird sticker. And whenever I sent him a message thanking him after our dates, he left me on read. When it was my papa’s birthday, he told me to celebrate with him if I didn’t have any plans. So I spent the day with him and gave him a present, but all he said was, “You’ve got good taste, haha.” He didn’t say thank you even once. At first, I thought he was a cheerful older man, and I really liked him as a papa. But little by little, I came to see him as a self-centered old man who couldn’t show gratitude, and I started disliking him. I recently ended things with him. Even if it’s a papa-katsu (compensated dating in Japan) relationship, gratitude and respect are still necessary, right? Even if you feel grateful inside, the other person won’t know unless you express it.
