I want this time to be different

I hope I've got this right, can't seem to get my posts to post, lol. I'm on day 1, tried all the patches,stop smoking now, gum, etc. etc. My husband's quitting with me, well, trying to. Problem is, every single time, same thing, we get in a huge fight, and then we run to the store to buy another pack of cigarettes. Already today, he doesn't want to talk, it hurts my feelings,stop smoking, because I think we should be each other's support system, then I get offended, and he says I'm starting a fight, etc. etc. etc....same thing different try. What do I do? I've accepted that I want to quit whether he does or not, but how do we get through this week without killing each other? I'm dreading going home.
