How to accept smoking


Going into my relationship, we both smoked cigarettes. 4 years later I have quit. He has moved onto cigars. Which smells better than cigarettes, but now the smell is very overwhelming. I can understand how hard it is to quit, but now I am wondering how do I handle him still smoking. I can let him be who he is……accept the fact that he smokes, but the smell of him kind of turns me off. He flat out stinks.
We also smoked in our basement, which was vented outside, but our house now stinks all the time. Accepting that he smokes I can do, but how can I accept how it makes my home smells and how he smells, which is like an ashtray.
