Sort of related, when I got married to my wife, at the rehearsal I told the pastor I wanted him to say “I present [my first name] and [her first name] [my last name]” at the end instead of “[her first name] and [my full name]” (the latter of which is how he was going to word it, probably because he was her pastor and it was her parents’ church). They both gave me a look when I said that like I was asserting myself over her by putting my first name first, so I had to explain that I simply liked putting her first name with my last name.
So you were doubling down on your sense of ownership? 😉
But seriously,!I’m betting she really likes having your name.
