Do you think my boyfriend is loyal/honest with me??

[Jojo]

I'm having a hard time trusting my boyfriend. Not really because anything he's done. But because I'm paranoid bc I've been done wrong so many times in the past.

The only thing I know that he's done to me for sure is I caught him texting his ex 3 months into our relationship but we've been together for almost a year now.

We broke up a month ago (it was sort of mutual) bc we argued so much. And exactly a week later (after NO contact) he texts me and says he misses me and wants his girlfriend back and that he's miserable. And we met up that night and discussed a bunch of things we'd need to do if we were going to be together again. Most of the things were HIS idea. Like no drinking without each other, no more social media etc..

Do you think I can trust him? I really want to. And I don't see why he would go behind my back and do those things if he could've just stayed single. But you never know.. Ya know?
