How would knowing exactly what he meant in the moment he said that help? Then you mind would go to does he still think that. I know it's hard to let go of all the thoughts that can clutter your mind. I struggle with it all the time. Mostly I find something to do that takes my mind in another direction (if I have to....crunches).
I hope you have a great time this weekend. Try to keep the focus on you and your friends and leave as little space for him in your brain as you can.
