I’ve never had a girlfriend who told me to quit. BUT when I was 17, my grandmother – God rest her soul – was sat with me in her living room. She smoked like a train. If it wasn’t 20 a day, it might have been 30 or more. Anyway..she gave me this really disapproving glance, and then told me to give up smoking. I didn’t give up smoking because at that time it was my choice and I was sticking to it. Since smoking for 15 years is never likely to do anyone any good, I decided to quit in August. I can see where all the fuss comes from when non-smokers kick up a stink about it. I think it can either help, or hinder. Depends on how the situation is approached and when. If you want to be rid of the stink in the meantime, maybe you could try to persuade him to get an e-cigarette. No stink, just nicotine in water vapor basically.
