The smug look in his face when I handed it back and he said found anything?
My cheating liar one year on (and I thought remorseful but as it turns out... resourceful) has been voluntarily sharing his passwords, handing over his phone, even made me a cloned iPad which would do and receive everything he did ... I said well you could have another burner phone or a KIk account or whatever (I have spent too long on MN) but he was doing everything he could to prove his trustworthiness and openness. I kept likening it to magician waving brightly coloured cloths with one hand so you don't look at the other.... Two months later when I finally got confirmation that he was not only still seeing and sleeping with OW that he swore he wasn't but was lying to her in a full on love affair where she thought they were going to start trying for children. And he conducted this all through his normal accounts! It really was the magician act I said it was. He has clarified now that he would delete everything as soon as it arrived, and he gets notifications on his watch so would be pdq. And would have bursts of conversation when he knew I was otherwise engaged, then would turn to airplane mode once he couldn't be there to monitor, knowing I would think he was underground or asleep! Must have been some adrenaline trip.
Anyway, what I wanted to say is that you should keep your cards close to your chest. Because if there was a chance that you tried again then he would know all the tricks, and if he doesn't know about Google timeline then for god's sake dont tell him.
Mine just absorbed everything I used to gather information last year and claimed to have changed, but actually he used that info to turn off back ups, uninstall reinstall and delete frequently so that even sophisticated spying programmes that he gave me permission to use (to prove his innocence 
) didn't bring back anything.
I now feel like I have lost my mind having spent so long trying to prove something that he was such an expert at hiding. So gather your evidence, but don't show it. Just say you.know he was at the premier inn on given dates and times. You could have got that information a number of ways!
