For background I have access to my partners phone / location / Instagram and Facebook regularly. So if he was going to hide something he would know he needs to be clever.
A while ago my DP had an older iPhone and it had no memory and was at the end of its life. Apps kept going onto the cloud due to lack of memory and one of these was Snapchat. He said that he deleted it as there was no point and I thought nothing of it. I had seen his snapchat before, barely used, not as popular among his friends.
Then a few weeks later snapchat is back, I commented on this. He said it automatically downloaded again with the software update. He had had a software update and seemed like a typical iPhone issue so just accepted it. Couldn't see anything incriminating, then he deleted it again as I thought it was odd how he didn't want it and then suddenly did.
Anyway, now he has a new iPhone. One night a few weeks ago, he fell asleep so I got his phone to set his alarm for work (when this happens he usually sleeps through). When I double tapped the home button the App Store had been open with "snapchat" in the search bar. I thought it was odd. I know the password so I downloaded it on my phone and logged in to see if anything suspicious was there - nothing was. So I then asked him about it and he said he'd gone on to see something he'd read about Cardi B (he's obsessed with her) then deleted it after. This sounded odd but I accepted his word as I hadn't seen anything when I'd looked.
Then last night, he fell asleep again. I got his phone and I swiped to the left where it shows "Siri app suggestions" and for half a second snapchat was one, it then disappeared as the app had since been deleted. A small glitch that occurs when you've had an app and then deleted it but from experience you have to have had the app/used it most recently.
The reason this makes me think he's cheating is because I've been logged into his snapchat on my phone since the issue of the App Store and if you log in on another device it would have signed me out. Therefore I know he hasn't been on his account. This means he has another one and the only reason for a secret account is not good...! I asked him and he denied ever going on it since our last discussion.
I'm at a loss at what to do/believe! Anyone got ideas/advice? My gut has a bad feeling on this
