May the Gods help you both . I cannot imagine living in a home with a smoker . Let alone living with the 4 pack a day habit . You are both in a poisonous atmosphere. I smoked for too many years myself . I stopped smoking in my house. in 1992. I stopped smoking completely in 2002. I have stage 4 Emphysema. You should put your health first . There are many other harms for your body when you smoke . Sounds like your husband has given up . Blessed Be, Crystalina
