Does anyone else dislike George?
He's fickle as hell. One minute he's willing to start a life with Nina, then gets his head turned very easily by Paul, but still tries to keep her on a string until she finally has enough and won't let him go on using her as his backup plan. I think the scene that bothered me the most was after Thanksgiving dinner was over, she's washing the dishes, and he says "I love you" to Nina, and then proceeds to take his lover into the bedroom right in front of her.
In the end, it just seemed like he was basically using her to fill his idle time.
