This guy im dating who is 16 (im 17) parties a lot and has a high tolerance for drinking?

hi so there's this guy i've been dating for like two months and we have known each other since january. here's the deal....ok so i think i made a mistake with this boy that i am dating. i told him at first that i didnt want him drinking cuz he is too young and then we met this weekend. we went to go see a movie with him and my cousins but after they were all pitching in for money of "afterwards" so after the movie when i got home. i texted him stuff like you know that i'm here for you but for this to work there has to trust and for there to be trust there needs to be honesty. i know it wasnt a big deal for him to tell me at the time but not tell me its kinda not fair. i told him i hope he doesnt drink but when he does if he could tell me. and then asked him to say how much he is drinkin. sayin is different from doin and doing is different from believing. i feel like i was being overbearing but his brother doesnt do anything about it. and his parents don't even know about him drinking and partying. i wasnt trying to be mean i was just trying to look out for what's best for him. maybe whatever is between us isnt the best? maybe we wont work out because i am being controlling and overpowering. even though i love him i cant tell him what to do. he isnt like my sibling who i do have some control over. He isnt my family who i can be up front with matters like these. its hard to express one's self when we don't have the right words to express it. he hasnt been talking to me and i cant help but feel really bad about it. i want to say im sorry but i dont really feel sorry because thats what i feel. i guesss i was being a hypocrite because telling him not to drink is just mean especially cuz he is like one year younger than me and he is a lot more mature and knows when to drink and how much. i want to say something but i dont want to look desperate and asking anyone about his thing is just going to create more drama. . i feel like he hatesme but this is a part of me that still dwells in wanting to change others to fit my expectations. im not sure of myself and he can see that. im scared that im exposed and seen as a *****. i want to make things right. he is toooo nice of a guy to let go of but then again his niciness can only lead him so far.
