Hello, I have a recent dilema sorta that I need a little help on. I would ask my friends but I don't want them to have a bad opinion of him.

Before me, he lived with his ex-girlfriend, his best-friend and his girlfriend. These people are into raving and partying. I have no issue with that. His friend is a really nice guy but i'm starting to notice they really like their drugs too much. They find every excuse to get high. I'd say every time i've seen them they've at least smoked pot. With this, I don't have an issue...What I do have an issue with is their ecstacy usage. And my boyfriend was into it too. When we first started dating, he told me he's over it. That type of life style and culture is absaloutely not my thing. But these are his friends and I accept that but do not accept that he's been doing it too. He's only done it three times...Twice with me, once after he said he wouldn't and I told him after the last time I am not comfortable with him doing it and it's not part of my life style. He said he understands and won't do it anymore. Last night, he brought up doing e on new years. He says, "i can do drugs if I want" and I said, "that's fine, then you can celebrate by yourself because I won't be there..I'm not going to be around my boyfriend high when i'm uncomfortable with the situation" he said nothing but sighed a few times and fell asleep. I have to talk to him about how serious I am that this is not my choice in life style and I will not be with someone that does e and these people put nothing but a bad influence on him. What should I say to him that will really make him understand this is not cool with me and not seem like i'm telling him what to do but that if he chooses to be with me, he has to leave his past behind!
