AIBU, not asking DH to evening wedding reception?

[HaveNoTimeToThinkOfName]

Just mentioned to DH that I and female colleagues (work in a nursery) have been invited to a childs mums wedding in the evening. We were quite surprised we had been asked as don't know her any more than any other parents, but at the same time chuffed she felt she wanted to ask us. He thinks it is odd that I am contemplating going as never spoken about her before and weddings should be with partners if you have one. AIBU? I hadn't thought it was odd until he said and I'm now doubting it! I was just seeing it as a night out with work colleagues I guess!

something screams free childcare!!! to me.

Rainbunny, what on earth is PC about the potential rules in question? Possibly over-formal, yes, but PC? How?

Yeah was my immediate thought kids at weddings parents wanting to party ooo free childcare

Thanks for replies, nice to hear everyones point of view. Sukistjames I hadn't even thought of that! I'm still not sure whether to go or not, I would feel guilty not going though I think. Some of my colleagues don't have partners or children so are happy to just go, feels a bit odd to me I must admit as we don't know her any more than any other parent. She is a bit chatty and has obviously been excited telling us her plans over the last year but only briefly at the door! I certainly didn't expect to be invited so definitely wouldn't expect DH to be! I was just surprised at his reaction when I told him, bit old fashioned viewpoint maybe?! Thank again.

First thing I thought was free childcare, or she wants more wedding presesnts/cash. I'm inviting people to my wedding from a group I know, not inviting partners unless I know them personally.
