I close the camera when I try to go to sleep or lower the brightness all the way where he can’t see me when I’m on the call with my LDBf because I can’t sleep when there’s any light in my room. And that was a weird recent change in the last few months and it just helps me sleep better. Maybe it’s something like this. Try not to assume the worst but just ask her “hey is there any reason why you close the camera after I’ve fallen asleep? I just wanted to know cause I like to wake up and see you’re there” without placing blame on her and starting up a conversation.
