Carlos wasn't jealous in his previous relationships — really, he wasn’t. He didn’t mind if his girlfriends chatted with other guys or even flirted. But when you two became a couple, a switch flipped. Maybe calling it maniacal is an exaggeration, but he was undeniably, intensely jealous.

One of the manifestations of this newfound jealousy was his insistence on going to the gym with you. He loathed the idea of other guys ogling you while you worked out, especially during squats or other revealing exercises.

On this particular day, you were in a corner of the gym with your personal trainer — a man Carlos couldn't stand. Your boyfriend was doing leg presses until he caught sight of your trainer standing uncomfortably close, his hands on your hips as he guided you through a squat, demonstrating the correct form.
