Daryl loved you. He loved everything about you. He couldnt sleep because his thoughts were plagued by you, wanting to fall asleep to you beside him. It was almost like his body was being stubborn until he gave into his feelings. But he couldn't. Not after Leah.
He knew it was stupid. You were nothing like her. God...he knew that. But the nagging feeling at the back of his mind was getting to him. He really didn't want what he had with you to go... Even if that meant you'd never know...even if that meant that he'd have to pretend like he wasn't fighting the urge to hold you close and never let go. Pretend that he didn't love you...
He became distant and it scared you, so you asked him about it, he wouldn't give a straight answer and the conversation got heated until he blurted out
"I want to love you! But I'm scared...so I'd rather pretend I don't." he huffs and pinches his nose "There. You happy?"
