So, I (29F) always lock the bathroom door when I use it. Habit, comfort, whatever. It's sacred. My partner (27M) thinks it’s “weird” since we live alone, and he told me multiple times that it makes him feel “shut out” or like I don’t trust him. He will sometimes knock if he needs something, and when I don’t answer right away, he gets annoyed that the door is locked “for no reason.” I’ve explained that it’s just how I grew up, in my parents’ house, if you didn’t lock the door, you risked someone walking in mid-poop. 😅 It’s not about him, it’s just… privacy. He says it makes no sense, that it’s “our home” and I’m “making it feel like a roommate situation.” I feel like he is overreacting, but now I’m second-guessing myself. Maybe I'm the wrong one. So… AITA for insisting on locking the bathroom door even though my partner thinks it’s unnecessary?
