So ladies is this a little sketchy to you

Recently I’ve noticed that my bf tends to put his phone on airplane mode. Now I’m not saying on and off through the day but when he goes to sleep he’ll do it or if it’s just him taking a nap and I’m awake also when he leaves it charging.

Some time ago he was in the wrong for doing something that involved another girl and he knows he was in the wrong and there was absolutely no reason for doing what he did.

Before this happened I would constantly hear his phone buzz from all the notifications he gets...I know a majority of them from Snapchat. Anyways he wouldn’t put his phone on airplane mode at night I know because I don’t get very solid sleep at night and wake up here and there and I would hear his phone buzz or feel it buzz when he keeps the phone under his pillow or sweats ( now that I think about it it’s a little strange to have it zipped into his pocket when he’s laying down)

So ever since I’ve been suspicious and I really don’t want to be but ever since that day there’s this switch in me that flipped on and it’s like there’s an itch in me to look through his phone however he uses Touch ID and I don’t know his actual passcode.

I know I can ask but how do I really know he’s being honest?

And is this even something I should be concerned about?
