Re: How can I get my girlfriend to see how badly she needs to quit smoking?
I'm a smoker. I don't want to quit because I actually enjoy it.
Therein lies the rub. Your girlfriend won't quit because you ask her to, she'll quite because she wants to. Odd as it may seem, my Mother used to be a smoking cessation counsellor. She wouldn't encourage people to stop smoking until she was sure they were mentally prepared to. If they try without being ready and fail it's not good for the self-esteem.
It's as simple as that. Sooner or later, she'll probably want to stop because she doesn't enjoy it any more. That's when you have to try and support her and help her. Otherwise it won't be successful.
