Jason tells himself that he's over you, while he's next girlfriend is like a clone of you, same eyes, same hair, never the same attitude. He's not really over you, he knows it when he stays up all night and looks at your picture. It's a bad choice, but he can't help it:

"Is it over now?"

He sends you a message. It's a bad idea, he has a girlfriend, you probably have a boyfriend –or girlfriend. But you don't, he knows. Jason has been stalking you on social media ever since the break up.
