Your girl doesn't live here

Justin had been blowing up Marissa's phone ever since the breakup. It had been a week but he wouldn't back down. Marissa read every of his messages but replied to none. She didn't pick up his calls either. She had the urge to listen to him sometimes but she had to stand her ground. 

Justin showed up at Aaron's house that particular evening to see her. He was met with Aaron instead of her. Aaron didn't look very pleased to see him and Justin just wanted him to get out of his face so he could talk to Marissa. 

"Is Marissa in? I wanna see her." He said, with his hands snug into his jeans. 

"What are you doing here man?Please go home." Aaron told him flatly. 

"Just  kindly move out of my way. I don't have energy for this. I want to see my girl" Justin replied with maddening calm.. 

"Your girl?" Aaron repeated and gave a lopsided smile. "That girl of yours doesn't live here."

"What exactly is your problem?"
