I hate smoking. I always said I would never date a smoker, but my current boyfriend hid the fact that he smoked from me for about 7 months (I honestly don't know how he did it but he did). He knows I hate smokers. 
When I found out he smoked I was mad and I have told him that I'd like him to quit but I'm not super pushy about him having to give it up because idk it's his body right? I have asked that he doesn't smoke around me though. I hate it, I hate seeing him smoke, I hate the smell, and it makes me cough like crazy. We've had multiple fights because he keeps smoking around me even after me asking him not to. Sometimes it's outdoors which isn't so bad, but sometimes it's in the house, in the bedroom even. I hate it.
