He forgot my birthday.

We’ve been involved for 9 years. This is the 2nd year he’s forgotten (he forgot in 2023 as well). I expressed to him it hurts my feelings and why. This is part of our text chain about it:

Me: I think I've realized I'm just a texting buddy to you when it's convenient. It takes 10 seconds to send a happy birthday text. I thought I meant more to you than that.

Him: I’m sorry for messing up your birthday. I've known all month that your birthday was on Sunday. Then I spaced on what day it was. I do that a lot. That doesn't make it better.

I messaged you on Saturday night and never heard back. So I figured you were off having a fun weekend.

Today 9:08 AM Happy Wednesday. On a scale of 1 to I'm not writing him back how mad are you at me?

Is he just a dumb? Do I just give up and not respond after 9 years? It’s just been one disappointment after another lately. He’s been doing a number of things in the past year that make me think he doesn’t really care anymore, this was just the cherry on top.
