I agree that it should not be normalized, but calling it pathological is a pretty callous description for it. I have had many girlfriends go through my phones and I really had nothing that was upset them, so I didn’t care, but I was always curious. The more I understood it, the checking comes from insecurity that is rooted in trauma. They did it in an effort to protect themselves from being hurt. It was not logical to me because I had given no reason to have them doubt; but the level of hurt and distrust caused them to have extremely careful precautions.
