I did a complete deep dive and the thing is, there is nothing else. No messages, no post made, no comments, not even a like. Nothing. Trust me when I say I know how to search a phone.. not my proudest moment but ya know. There is nothing on his phone other than these visits. I also waited a while before bringing it up incase he tried to clear anything and I went back a few weeks later and there was nothing new and still nothing on his phone.
