We use our names but we have other things too. We aren't married yet but he will call Mrs (his last name), it's cute and I love it. He calls me babe or pretty girl.
I call him babe too or handsome man lol.
My Goddaughter says his name so cute, she can't pronounce it correctly yet so I started calling him that too haha. I have another one but he has an account on here and I don't think he wants me to tell it lol.
