aibu to expect DH to come to my friends wedding?

[sheepflower]

An old school friend I am close to invited us to her wedding. When I told DH he said he wasn't going and DD and I can go our own. We haven't been getting on that well for a while but are having counselling and I thought things were improving.
Maybe IABU to automatically expect him to come. They are really 'my' friends although DH has also known them for over 10 years now. There's no argument between the friends and DD but I suppose he doesn't like them as much as I do and they're not particularly close. But even so, seems a bit of an odd reaction and left me a bit gobsmacked.

I've never, ever been to a wedding where there weren't a few 'one half of a couples' and there can be lots of reasons why it ends up that only one half goes to a wedding (finances, inability to get childcare, sick etc). That's life. If the single half is comfortable about going alone, it's not a big deal and nobody would even notice.

Anyway that's not the point here as OP has already said she doesn't mind going alone.
I think as others said, he could've been more polite about it but also, from the little you've said, I fear he just doesn't want to spend a day with you, which makes me think you're not both on the same page about your relationship.

But if you want to be part of a couple that does lots together OP, that's your entitlement. It's not wrong to want that. I already said that DH and I do plenty apart by choice, but we also do stuff together, and that's the difference between the two scenarios. If he fundamentally doesn't want coupledom with you and can't be arsed even paying lip service to the idea by being polite about something like this, that's a different issue.

YANBU. It's the rude refusal that seems so unnecessary. There are perfectly reasonable ways of saying that you'd rather give a particular event a miss but this wasn't one of them.
