No birthday acknowledgement

[primroser]

It's my 30th birthday today. I have been seeing a guy for the last three months. It's been quite casual, meeting once or twice a week and just generally enjoying getting to know each other slowly.
He knows it's my birthday today as I mentioned it last week when I saw him. I couldn't see him over the weekend as I had plans with family.
He text me my usual "Good morning, have a great day" message this morning. No happy birthdays and no other contact today (which isn't in itself unusual occasionally).

AIBU to expect him to acknowledge my birthday, maybe even send a card or flowers? Or at least wish me a happy birthday?!

I'd say he forgot! You could reply and say having a great birthday and see what he says

Maybe, but really? Forgetting a 30th birthday and we also talked over the weekend about what I was doing and it was all about my birthday celebrations with family.

Cardinal sin in a new relationship (or ANY relationship to be honest!)

I forget everyone's birthdays.
He hasn't known you long, it's a little upsetting maybe but it's not a big deal.

As he sent you the “usual” morning greeting, it just sounds like he’s forgotten, OP. And look, whilst that isn’t ideal and you might be disappointed, it’s easily done, don’t take it personally. When I’ve had a million things on at once and am trying to juggle everything in my head I’ve forgotten the birthdays of people I’m very close to, even when I’ve thought on several occasions in the preceding weeks and days that I must remember to send a text and pop a card in the post. I can see how easy it would be for the birthday of someone he’s just met to slip his mind.

I second NK1 - tell him what you’ve been doing with your day and it’s very likely you’ll get an apology and a happy birthday wish. Plus you only have to read threads on here by women who say their OH treated them “beautifully” at the beginning of the relationship and were always lavishing them with lovely gifts but soon turned into shitbags to realise that it isn’t the be all and end all.

He forgot.

Happy birthday !!!!
