Husbando is the only word I have ever heard used for this (other than just throwing gender to the wind and calling male characters waifu as well)

Husba works for me

Waifu is gender neutral.

I wish that it was darin (darling). It rolls off the tongue so much better.

What’s a waifu?

Husbando, it’s really just a japanese accent of saying wife and husband.

There’s also the alternative “grills” vs. bouys" pair.

Hubnob?

Husbando, yeah. I agree with you though, it’s not as fun to say.
