AITAH for walking out of my own birthday dinner because my girlfriend turned it into her celebration?

So my (25M) birthday was last weekend. I don’t usually do anything big, but this year a bunch of my friends were in town, and my girlfriend (23F) offered to plan something. I was genuinely excited. She made a dinner reservation at a nice place I’ve been wanting to try and said she had a little surprise planned.

The surprise was that she invited a bunch of her friends. Like, 6 of them. People I barely know. One of them I actively dislike because she used to hit on me when my girlfriend and I first started dating. My girlfriend brushed it off saying it would make things more fun and lively.

Whatever. I tried to roll with it.

But then at the dinner, it just got worse. She spent the entire time talking to her friends. I was seated at the far end of the table next to two people I’d never met. She didn’t even sit next to me. When the food came, they all toasted her for organising everything and started talking about her upcoming promotion. Her best friend gave a speech about how she deserves all the happiness in the world. Not one mention of me or my birthday. No cake, no toast, no happy birthday. Nothing.

I literally just sat there while everyone gushed over her for two hours.

Eventually I got up, paid for my portion of the meal, said I wasn’t feeling well, and left. I didn’t make a scene or yell. I just quietly left.

Later she texted me saying I embarrassed her in front of her friends and ruined the night. She said she tried really hard to make it special and I was being ungrateful. A few of her friends have messaged me saying I was being immature and that it wasn’t that deep.

But I don’t know, man. Is it crazy to think my birthday should’ve been at least a little about me?

AITAH?

Update:
We talked. She doubled down and said the dinner wasn’t just about me, it was a chance to celebrate us and her hard work planning it. She admitted she didn’t invite my friends because they wouldn’t vibe with her circle. Still no happy birthday, no apology, just told me I was being dramatic and should be thankful she even organised something. I guess the dinner really was all about her. So yeah, I ended things.
