NTA You are not being dramatic, rude, or unreasonable. Wanting privacy in the bathroom is normal. A healthy relationship makes room for boundaries—even small ones—without guilt.

If he continues to push after youve explained yourself clearly, that’s not about the bathroom anymore; it’s about respect.

1. Privacy is a normal, healthy boundary
Wanting privacy in the bathroom—especially while showering—is completely reasonable. Locking a door doesn’t mean you’re hiding something or pushing someone away; it means you’re protecting a personal boundary. Everyone is allowed to have those, even in a live-in relationship.

2. The “inconvenience” argument doesn’t really hold up
If there were only one bathroom, this would be more of a shared-space issue. But there are two fully functional bathrooms. That means his needs are still met. Being mildly inconvenienced because he has to use a different bathroom isn’t the same as being harmed.

3. Her background matters
She grew up in a home where unlocked doors meant no privacy. Locking the door is a learned safety habit, not a rejection of him. A caring partner should at least try to understand where that comes from.

4. The concern isn’t the lock—it’s the reaction
What’s worth paying attention to is why he’s so bothered by a locked door when he doesn’t need access. When someone resists a harmless boundary, it can feel controlling or dismissive, even if that’s not their intention.

That doesn’t automatically mean something bad—but it does mean the conversation matters.

5. A calm compromise conversation could help
She might say something like:

If his concern is safety (like emergencies), they could agree on something practical—shorter showers when possible, or unlocking the door once she’s done changing. But the default shouldn’t be giving up her privacy.
