Just talk to him like he's one of your friends. Offer him gum or something, or give him a compliament on his shoes/clothes/backpack whatever.
And hun, don't change yourself to fit his expectations. It's tempting to do, but he should like you for who you really are. *sniffle sniffle, drama* :'D
Good luck my dear; I've had this problem before so I know how you feel
