What happened to us?

Naruto decided to go home early for his 2nd anniversary with his boyfriend, Uchiha Itachi. And he had good news as well. He's pregnant!! But when he arrived home his boyfriend was laying in bed with someone else on top of him. His distant cousin, Uzumaki Karin was having sex with Itachi. Immediately he bolted and never returned home. Will he tell Itachi of his son or will he never tell him of his own off spring?
