After she left, he went to bed to try to get some sleep but it was no good, he tossed and turned all night, replaying the events of that night over and over again thinking about what went wrong and caused those sad eyes in his beloved Amy's face,
Next morning he followed his usual routine but found himself looking at the picture they took at prom that he kept in his bedroom, hidden in his comic books. He thought about his panic attack, on how he freaked out when he saw her leaving Penny's house, when he didn't let her go inside his room , truth be told it was because being in the same bedroom as she would be very difficult to resist the urge to kiss her breath away. He never told her that was the reason why, he simply told it was because she looked that pretty; he knew he loved her, just didn't know when to tell her without causing a major scene and when she started talking, that was it.
Now, they were making out in his couch, he wasn't in his spot, his hands knew where to go and he didn't have to think about it, it was like a second nature to him and that is what scared him. The fact that touching Amy has become too natural to him, just like breathing or eating or even go to the comic book store and that was something he had never consider.
He sat on the couch watching the Doctor Who episode he had started watching but he started thinking about Amy he immediately stopped paying attention.
He finished watching the episode and started walking back and forth until he realized it. She had left because she thought she wasn't constantly on his mind, that couldn't be more false. He grabbed his jacket, put on his bus pants and got out of the apartment.
When he arrived at Amy's apartment he knocked his usual 3 times and she opened the door, her eyes were red like she's been crying
'Sheldon, what are you doing here?' She was genuinely surprised to see him standing in front of her
'Have you been crying?'
'Sheldon go home' She attempts to close the door but his foot stopped her
'Answer me, have you been crying?'
'It's none of your business, I asked for a break so please, go home'
He could see the tears forming in her eyes and it was eating him inside, specially the fact that he was the cause
'I'm not leaving this place until you answer me!'
'If that's what you want.. yes I've been crying, now goodbye Sheldon'
He takes a step back and allows her to close the door, he was staring at her door unsure of what to do next, so he do what he could to make her stop crying, he grabbed his wallet and grabbed his emergency key to her apartment and entered, he could hear her cries in the bedroom
'Sheldon, what the hell, I want you out of my house. NOW!'
She wanted him out but didn't leave her bedroom, so he decided to push his luck and cross those tardis doors.
