One night, you're sitting on his lap and he's really focused on his computer, but you're playing on your phone and smiling to yourself, he sees you're exchanging numbers with another guy, he gets annoyed then grabs your phone and throws it across the room

"Who was that guy? Why did you exchange numbers with him? Do you want me to throw away your phone? Don't exchange numbers with another guy again." He snaps at you coldly and continues playing games on his computer
