Locked phones

I went through my boyfriends phone and told him that I did, now he's put a lock on it so I can't get into it. Not that i want to go into again but it makes me feel like he's got something to hide. He knows my passcode and I really wouldn't care if he was going through mine. Maybe I'm crazy and overthinking idk

-the reason I went through it is Bc I'm a nosey bitch.

-we had been fighting and I just wanted to see how he spoke to women before me.

-I did find messages to an ex telling her how he fucked up and she was the one that got away, this being while we were dating but a month shy of us starting our relationship.
