If you're trying to quit and he really likes you, then he'll support you and try to help. Think about if smoking is worth not taking the chance you have to be with this guy. My friend uses this nicotine gum to quit smoking and it really helps him. I suggest you try that and if things don't work out with the guy, you always have the choice to go back to smoking or not:)
If you continue smoking you won't be a 'littlecutie' for long. You'll cough and have saggy skin and have a hole in your neck. You'll have half of your jaw and no flesh in your neck. YOU GOTTA STOP. Boyfriend or not.
