My boyfriend hasn't bought me anything, including flowers which I've asked for. Why?

I'm in my late 30s dating same age guy for 4 months. He's wealthy, I'm not but pay for around 1/3 of our dates (we don't go out often because pandemic).
When he hadn't yet, I sat him down and directly asked him to buy me flowers about a month ago, he still hasn't (so it's *not* a communication issue!). He claims to be super into me and we both think this is our lifetime relationship.
I've got him expensive and thoughtful gifts, he's got me nothing (even though I've hinted). I'm talking needing a new screen protector for $10 and he sent me a link instead of ordering for me. He makes about 6 times my salary.
I'm not a gold digger, and I get that gift giving isn't his "love language" but JC it makes me feel unwanted or cared for.
I think asking him straight out "I really like flowers, I'd really like you to buy them for me, randomly or special occasions, here are some that I like" is enough and I shouldn't have to ask again but it seems like my directly asking didn't get through.
So... is there a way to get through to my boyfriend that I want him to buy me flowers and thoughtful gifts?
