I am a super blunt person, so my loud ass would've probably told him to chill the first time lol. It all just depends on how much jokey sarcasm your partner can handle lol! If he flips out though, then that is def a red flag, bc what does he think, you're just cheating on him 24/7 if he doesn't have you hostage on the phone?! You'd look like a jerk if you phone's going off every 5 seconds in a restaurant, esp with friends. And who wants to stop reps every 5 secs at the gym do their bf doesn't start calling them constantly? Mute the phone sometimes babe, you'll not regret it lol.
