it's been over a year

The husband used to smoke. He stopped years before we met and was doing pretty good until about a year in our marriage. He went back to smoking for a couple years but he decided to quit again hoping that this time he will not go back to it again. He said is doing it for the kids and I am happy. He was not a heavy smoker when he did. He never tried anything like Acid cigars, he stayed with cigarette. Right now he is doing good. It has been over a year since he quit smoking and he told me there are days he still craves for it but he tries to control himself because quitting is hard and he does not want to go through all that over again. I don't know if it is hard nor will I understand how it feels, but I am glad he made the decision to quit.
