AIBU to feel upset that DH's birthday trip excludes me and the kids

[Yomuma]

As a birthday present a couple of moniths back, a family member bought DH a voucher for a fun group activity. It is for 8 people,and involves a weekend away. We planned to take our 2 teens and invite 4 others, either friends or family, we hadn't decided yet. Kids were excited to go. Then today the family member sends a message on a group family chat inviting 3 of DHs cousins (who DH rarely sees) and their partners to go with them and DH. No invite for me or the kids. They have all accepted, so no places left - so now I need to tell the kids they arent going after all.
AIBU to think it is a bit rude to buy someone a voucher, then just invite people and not invite his wife or kids without even checking first?
Even if the invite had gone to just the 3 cousins, not their partners, that would leave 3 spots for me and the kids. For context, DH and the family member have met the partners once at a funeral. Just feels a bit hurtful. We have been married for 16 years. DH doesnt want any drama so will go with the flow, but agrees it is all quite odd.
We are seeing this family member this weekend, not sure if to say anything? Even just a sarcastic "thanks for the invite" type comment.

a voucher for 8 people sounds very generous, whatever the activity.

my theory is that the gift was never intended to be “a voucher for 8 people” and instead the relative only ever intended to invite the DH. But they wanted it to sound like they were being extremely generous.

@Yomuma Exactly.

Let's say the activity costs £50 per person.
Who buys a £400 present for another person unless they are absolutely minted?

Even a £25 activity would mean a £200 present - that's still a very expensive gift.

Does the gift giver usually do things like this?

You are just projecting your family's situation onto OP with no evidence to make that claim.

Or, you are just one of those posters who will always find a way to blame the OP and assume that she is in the wrong.

Because OP's DH, the birthday boy, was going to use his birthday gift for himself, OP and their children:

'We planned to take our 2 teens and invite 4 others, either friends or family, we hadn't decided yet. Kids were excited to go.'

You are being very weird about this and projecting your (female) relative's situation onto OP's husband and you are basically saying that OP is abusive to her husband based on no evidence at all.

Seems unlikely. I’ve paid for vouchers for people before and never had it. Either way she can just bluff and say it’s already booked!

It’s just another theory.
Clearly this situation does arise. Op can ignore uf it’s not relevant.

'Thank you very much for the thoughtful gift but in this instance I have to decline'..

@Yomuma have you received further clarity yet?
Has your DH spoken/ contacted the gift giver?
Was the gift 1 ticket or 8 tickets?

Ffs the husband has spoken to his family and arranged this. Thats why he says to just go with the flow.

Who told you he was going to? The OP? Is this the same man who said they should just go with the flow?

No my cousins were people I grew up with and saw nearly every weekend. We spent loads of time with our grandparents right up to when they died when i was a young adult. Some I dont see very often now due to where they live but I've known those family members of mine longer than I've known my partner.

Wife can be divorced and no longer be wife. Cousins are for life.

Simple responses “Hi sounds good , will they be booking themselves? I’ve already allocated the voucher places “

Fair enough - I know that plenty of people are close to their cousins; but equally plenty are not.

Hope your dh has set them straight op!
