I've written it before but I gladly repeat that I hope you find that, too.

I get that with the phone. It is tough to trust again after having your trust broken.

In my not so small personal experience, backed up by reading a lot, most adults follow certain behavioral patterns.

Most people have several life crisis as an adult. Divorce or a major breakup is one of them. How people handle the situation: before, during, and after usually follows a pattern they have developed over years, often decades. There are serial cheaters like your (and my) ex-friends. There are serial liars (huge spectrum here) and serial deniers (not the same) who blame the entire problem on their ex-partner, then go pick the same type of partner the next time.

I was a serial denier. Fortunately pattern recognition is something I'm really good at. Unfortunately I had a HUGE problem admitting an error (childhood trauma!) So it took multiple repeats for me to get back to therapy to try to figure out what I was doing that lead me to the same type of woman.

In the end I learned something from all those failures. As a gud boi once said, "Better to have eaten and thrown up and eaten again than never to have eaten at all" (or something like that). I personally would have preferred to skip the massive heartache and huge expenses and learned from someone else's mistakes, but my parents passed on their trauma to me. I do my best to fix my issues and teach our son how to avoid making the mistakes we made.
