I decided to go through my boyfriend’s phone. I don’t trust him he’s cheated on me before and has never given me proper reassurance since. He expects me to just move on and pretend nothing happened. I originally got suspicious because he started acting so weird with his phone, meaning, putting it under him when we’re laying down, sitting on it or keeping it in his lap when driving which he’ll usually put in the cup holders. I saw screenshots of messages in his recently deleted of him texting an escort or pornstar or someone of that nature interested in yk what. One screenshot showed him asking for verification that she was who she was and she said she would video call him. Is this something I should leave him for?
