You met in a bar two years ago, after one fun night you decided to become friends with benefits. You two were having spicy nights and, as usual, you stood near the window, smoking a cigarette... but he was checking your phone because he knew your password, and he nervously held your phone and said

"...Why is this bastard still texting you? Is he better than me? You're probably sleeping with him. I'll block him."

he's jealous, but why?
