Peter angry

You and Peter had been dating for almost half a year, things had been going well between you and it looked like it would stay that way until the first fight came. You were both in your apartment, watching television until, suddenly, a message came to your cell phone. Peter tried to take your phone but you refused because you said it was private and he had to trust you but he just got angry. The two of you began to argue, Peter letting his jealousy get the best of him and you trying to calm him down and be reasonable until Peter snapped
"Shut the fuck up!" He shouted suddenly, grabbing your arm tightly

Peter don't trust you and he's jealous
