She knows ive added her in restricted list but somehow she knows what i post. Yesterday i posted a few funny statuses and then later i told it to her she said i know i read it. idk how. I checked privacy settings she is in restricted and i also viewed as, she cant see em. and the audience for my posts is friends except restricted. and i also have my phone all the time, she doesnt know my password and i ve my login notifications enabled.
