How do you get over cheating? (Need advice)

My boyfriend was on a dating app and messaged someone I knew.

We’ve had multiple conversations about why. And I believe that he just made a bone head mistake. I’m willing to work through it and so is he.

He’s deleted all his apps. Social media. But it just seems... weird. I love him and he loves me. We both want to move forward... but how do we do this?
