"Handsome" although how it came about isn't very nice lol.
My mom got a shitzu bichone mixed puppy and he was super shaggy and I use to call him "handsome", when my FH decided to grow out his beard I said he looks like Kaptyn (the dogs actual name) so I started calling him handsome and it stuck.
Don't really have pet names. In texts we usually use babe. If I'm at his dad's I don't use his name at all lol. His dad calls him by his first name but he goes by his middle name so it messes him up if I use his first name.
We don’t really have pet names for each other, sometimes if we call to each other while in different parts of the house for what ever reason we say hun...but then it leads to neither one of us hearing and we just yell for each other using our names! 😆
We kind of sarcastically call each other "babe" all the time, but we actually refer to each other as bunny and bear. No clue why that ended up happening. He is actually getting a tattoo with a little geometric rabbit soon here that says "be kind". Apparently he feels he needs the reminder sometimes lol.
