She's discomforted and hesitant to him, especially by his touch. He's waiting for the awful truth, but she's locking it up somewhere. It's the somewhere that can't be reached, no matter how hard he tried. It doesn't mean he won't attempt to release it.
Why was life so complicated, that it made some things simple? Love was complex, holding something he couldn' understand. Yet, some answers were so easy to figure. This was the way he felt about everything about her; she held some unnatural truth that was hard to discover, yet some things of her were effortless.
'Tell me you don't love me,' he knows his attempt could fail.
Crying, she asks slowly, 'Why are you doing this to me, Severus?' He doesn't understand – her, holding that one thing he wants to know, yet bottling up inside, was painful for him.
'ANSWER ME!' he forces. She is crying harder now, and his expression softens. 'Just tell me, Lily. And then-'
'I don't love you.' A scar is forming on his very soul. The little secret inside her was just freed…and now he forgets to breathe for this first time.

"Severus! SEVERUS!" A jolt is shoved throughout his body, and he awakes with a start. The boy leaves his side and returns to his bed, grumbling something like, 'Dangit, do I hate yelling in the night.' Severus watches him go, and doesn't know what to feel right now - either grateful or angry, because maybe the nightmares are as close as he will ever get to her.
You paint me with colors, Lily, that I don't understand.
