Wedding invitation excluded wife

I received a text from a cousin. The only thing in the message was a link to a wedding website. After much head-scratching I determined that this was a wedding invitation and that I was invited to his wedding…but my wife’s name was not included.

My sisters were both invited along with their husbands. There is no animosity between any members of the family (that I know of,anyway) so I’m thinking this was an error. But I don’t want to just show up with my wife without making sure first.

How should I navigate this?

Thanks in advance, kind redditors!
