My dh is a heavy smoker. I hate it and the health risks he knows this but makes no effort to quit. It's ruining him his wrinkles round his eyes are like those of a pensioner and the most minging part is his teeth are going black and I can't bare to kiss him. It's going to sound so terribly shallow but I can't imagine being with him for the next say 30 odd years as he is now. How do I approach this subject??
