Also if you smoked cigars before getting married, I would ask myself why is this coming up now. Why is it getting worse? What is the reason? If you did, maybe she thought going in she could change you, but now seeing that she cant, she is gripping more trying harder to get you to quite.

Now I dont know anything about your situation, just throwing this out there, so if its completely off, then disregard it.

But the best advice I can give, seeing as Im not married, is to communicate. Communication is the basis of all relationships. If there is no communication, it is not a healthy relationship.
Ask her why she is complaining more and why she dislikes it to begin with. Then tell her why you enjoy it so much. Everything begins from here.
