Am I overthinking?

Kiara

Hey everyone! This is going to sound completely dumb but I really don’t have any friends I can vent to about this stuff. Anyways, in the past my s/o was extremely nasty towards me (cheating, lying and everything in between). But in the last 2 years he has made it a point to prove to me that he’s changed.. Now I’ve never been the type to go through phones but I knew his passcode, anyways, over the weekend we went out and because of the masks he had to input his passcode manually and I realized it was completely different! Like I said I never go through his phone so I don’t understand why he would even need to hide anything.... Am I overthinking or does this sound fishy? 🧐🤔
