AIW for expecting a small gathering for my 30th birthday?

It was my 30th birthday last month. Prior to this my girlfriend asked me what I wanted from her and I said I'd like a small get together of just a few close family and friends so if she could organise that it would be great.

There's a bar near us that lets you book the place out for free if you have at least 10 people as it's a small place so I mentioned going there and she nodded and said okay.

My birthday came and I got nothing like that. I got a card and a couple of little gifts (2 gift cards and a book) from my gf but no gathering or any sort of celebration. I was upset at this and my girlfriend asked me why I was upset and I explained it to her.

She said it would have been a hassle trying to get everyone together and would have took a lot of work to organise.

I told her she knew how much it would have meant to me and that she literally asked what I wanted from her and then chose to ignore it. I said it hurts hearing her say I'm basically not worth any effort.

She said I should have done it myself then but I pointed out she literally asked what I wanted off her and I told her so why would I then go and do it myself when she didn’t say she wasn’t going to bother doing it. She said I was trying to guilt trip her but I told her I was just expressing how I felt about it.

She said I was being too unfair and that I should be happy with what I got. I told her she doesn't get to tell me when I can and can't be upset and that it obviously hurts knowing your partner doesn't care enough to even try to organise what I wanted for my birthday.

She again said I was guilt tripping her and deliberately trying to make her feel bad.
