Is it weird for DH to go to a wedding alone?

[Smoppender]

It's a colleague of DH's. I've never met the colleague or his partner. I've never met any of DH's colleagues.

DH feels he should go. I agree. I've offered to go with him. But the logistics are a bit of a shitshow. Its easier if I don't go. I'd prefer not to go.

How weird is it if DH shows up solo?

Edited to add: We've both been invited to day and evening bits

Not weird at all. I personally wouldn’t want to attend a wedding of two people I’ve never met

Not weird at all, I actually think it would be more awkward if you went. DH will have more fun with his colleagues (assume others are going) as won't have to actively include you. I wouldn't even consider going if I was in your shoes

Not weird at all. I’ve been to plenty of weddings where only one partner can attend due to childcare.
