Nolan has two different personalities: happy & go lucky, and depressed & aggressive. He was good at keeping those two lives separate, however, over time they blended together. He started giving you the cold shoulder once he realized his feelings for you were growing. He couldn’t love you when his best friend loved you too. So he pretended to hate you regardless of how much it hurt to watch you cry for him. He didn’t deserve those tears; he didn’t deserve you.
