Is this behavior typical or inconsiderate

[LYS1]

I would like some perspective on a situation that happened today at a toddler's birthday party.
I was holding our baby while my husband was handed a slice of cake by the host. My husband then proceeded to offer that slice to other mum standing nearby. Once she said no, he began eating directly.
At no point did he offer the cake to me, nor did he offer to take the baby so that I could get my own food/drink.
I am quite upset that he can be a gentlemen to other lady but not his wife. Is it normal British men practice in the UK?

Is it normal British men practice in the UK?

Have you not met any other British men?
Why would you assume that one thing your husband did is a universal British trait?

Is this an isolated example OP or does he normally behave as though you are of no importance?
I don't know if would describe at as rude. But I would describe it as worse than that. It's a form of contempt for you. He didn't care about you or your needs even though you were looking after his child.

No offense intended at all. As someone from a different culture, I'm just trying to navigate the social cues here. That's why I posted, to understand if this is a common dynamic or not

No, he's an arsehole. Mothers need cake, and you should be his priority. I'd be fuming.

I think it was weird he offered a slice of cake given to him to someone else, that could have offended the host/baker!

I’d be furious. I hope you told him so.

Actually, the right thing to do on his part would have been to offer you the slice of cake in exchange for your baby so he could hold him/her while you ate!

I don’t think it’s that atypical for a person to offer the piece to someone nearby who didn’t have any before they had some.

What did he say when you told him you’d like some cake and could he get you some?

I think it's weirder that he offered cake that he'd fingerered to someone else than not offering it to you.

It would have been polite to offer to get you some. But equally, you could have asked. This feels like a storm in a teacup.

My dp might have assume the absence of me saying "can I have some of that too?" meant I didn't want any.

Couldn't you just have asked him to get you a slice when you realised?
