Don't be rude and demanding with this guy, or you will chase him away. Sounds like he's being honest with you. He has his life to live and is busy. You AREN'T dating yet. You AREN'T a couple yet, so demanding his focus and insulting him buy accusing him of playing games is a real potential turn off. Chill a bit and let him get through the holidays and this time with his brother. You don't have rights over him at this point; don't act like you do.
