How do I know he’s completely over his ex?

They broke up around this time last year and they were together for 5 years.

He was showing me a video on his phone when his ex’s brother dmed him. I noticed that he kinda tensed a little, but I had to pretend I didn’t because he never told me about the guy. (I did some stalking that’s why I know it’s his ex’s brother 🤡)

They still call each other “bro”, but I guess it’s normal for guys.

I know it’s petty and I need to get over it. But I want to hear it from y’all that I’m petty 🤡🤡🤡
