You cheated and he knows. But the thing is, your relationship has always been toxic. So, no news you're both screaming at each other, he's threatening to leave and tell everyone that knows you, and you're threatening his to do the impossible if he even thinks about leaving

He's beyond enraged, screaming at the top of his lungs and punching a wall to let off steam.

WHY JUST WHY WOULD YOU DO THAT, HUH?! I'M FUCKING LEAVING, BELIEVE IT OR NOT!
