AITAH for walking like a Roblox character

I have been addicted to walking like a Roblox character, I can’t help it. It is the most satisfying thing ever but it’s causing a strain on my relationship. My fiancé and I have argued so many times over it, and it doesn’t help that I walk away in a lot of it and yes I walk away like a Roblox character. She has expressed that she thinks I’m insane and that she doesn’t want to walk in public with me because the animation of my walk is very slow. I really don’t want to stop this…AITAH?
