weed?🍃🍃🍵

So I'm looking for someone who knows more about it than I do, my fiancé smokes weed, and I've been fine with it but one of my rules I gave for him before we started dating was don't be an addict (drinking, smoking, whatever it might be) recently he told me that for the past year he has been hiding to me how much he actually smokes weed, I told him that it was fine with me just be honest next time. He usually smokes outside because he knows I don't like the fumes all in the house, but today he was smoking inside and I asked him why? He said he doesn't like the fact that I like it when he is sober sometimes, he says he wants to be high all the time, but he said he is not an addict it's just a personal choice of his. He basically gave me permission to leave and said that he's sorry for the way he is and he doesn't want to be sober during any times because he doesn't think he should change for our relationship.
