Ex still has location

Hi, idk if this is the right place or not but I need advice. I unshared my location with my ex on my iPhone, left the circle on life 360, and re set my wallets air tag. He once joked about making it so I couldn’t turn off my location for him and he somehow does still have my location. How does he have it and how do I turn it off?
