"He's being completely selfish" Aaron urged. "Think about it. What did he say to keep you? That he loves you? That he doesn't want to lose you? That he'll change for you?"

"...... yeah."

Aaron's frustration grew and he typed on his phone thinking of ways to emotionally and logically make Lisa realize what she has to do. She was so close to making the right decision, he couldn't let her slip away.

"But I'm more happy than unhappy with him."

What is she saying? Does she not realize that those two feelings do not balance each other out? She should not be unhappy at all, no matter how happy she is when she's with George. Defeated, Aaron decided to let her be. Maybe one day her unhappiness will outweigh her happiness.
