Give your waifu/husbando a superlative!
A lot of us are in love with some pretty exceptional people, and it can be good to recognize some of their most outstanding, unusual, or likable qualities!
If you're not sure what a superlative is, they're something you might commonly see in a school yearbook, saying something like:
"Most likely to succeed"
"Class clown"
"Most athletic"
And things like that! Feel free to get creative or think outside the box!
