Smokers who quit in a family of smokers have the same problems as dieters in a family of chubbies. Quitting/dieting isn't only your problem, but theirs as well. Your smoking validates your husband's smoking. He may see your quit as a rejection not only of cigarettes but of him as well. I went through the same things as a teen when I went on a diet. I was very very heavy and my mother who was not only heavy but morbidly obese took my wanting to lose weight as a personal attack against her. She fought me every way in the world using every tactic in the world including telling me how I would fail.
People who do this don't know they are doing it. They only feel really uncomfortable and want to end the discomfort. In this case, the discomfort is a change in you and an end to things you used to share, like smoking. As a quitter, you will be a different person, a non-smoker. It is a challenge for a smoker to live with someone who has quit, it is a fear that the new person won't be the same as the old person. That the non-smoker won't like them as well as they did as a smoker.
Your husband called your quit a "whim". That's something he thinks will go away on another whim. It's obvious that he is not taking your health problems seriously. This is common. If he takes YOUR health problems seriously, he will also have to take HIS health problems seriously, if not now, then at some point in the future. He's afraid. The next case of COPD might be his. If he can deny your illness and its cause (cigarettes) he can deny his own. You may not know it, but he might have had symptoms already and hiding them.
This dynamic is incredibly complex. Start with the fear and examine the situation from there, maybe it will help.
