The Human Doctor stormed out, slamming the door behind him. He couldn't take it right now. He couldn't take her right now. It had been a few months since she came into his life, in this world. He didn't know it at the time, but after he left, Rose cried herself to sleep once more. He wanted to run away from everything. He was tired of being someone he wasn't. He wanted to be himself.
He began to walk down the street, away from their home. He didn't bother to even grab his cell phone, he didn't want anyone. He wanted to be alone. And yet, he missed something.
He wished he wasn't stuck in this world; he wanted to be free once more. But his other self, the Doctor, didn't allow it.
The human doctor kicked an abandoned soda can further down the street. It made a soft clank as it hit the ground farther away. He sat down on a park bench and sighed as he gazed down at the ground, their fighting still stuck in his head.
"Just leave! Go!"
"Rose, just listen! You"
"You don't know what's its like to be left behind," She yelled at him, tears forming, swelling in her eyes. He tried to reason with her, but then he kept his mouth shut.
"Just leave," He did just that. He left.
The human doctor blinked and ran a hand through his hair as he tried to think. Some times things were stable, and then would crash apart terribly. He couldn't fix it. He wasn't him. If only he could make her happy again. Like the time they kissed for the first time, that was love.
