I am dumb enough to believe she only smokes when stressed so I believe she smokes a few cigarettes a day for a few days until the pack is gone. I believe she smokes when running errands and lunch hours and such when I am not around. She is smart ad sneaky and there is opportunity so it cant be stopped except by her own desire and integrity. Knowing that, I have tried very hard to accept it but it has effected my level of caring for her, the respect I have and of course the trust issues. She does not care how much it hurts me that she does it knowing how it effects me. She says it's my problem. My reaction effects the way I feel about her. It sorts of chips away at the intensity of love I had for her.
My guess is that she does not smoke much at all. Why? Because if she did, you would smell it on her clothing, mouth and skin.
She probably promised you that she would stop with good intent but cannot do it because they are filling a need for him.
I know that some people have switched to ecigs and then used them to stop smoking over time. Every person I know who has switched to ecigs has had significant health improvements.. they have lost the cough, are able to breath a lot better, can taste food and have a much better sense of smell. And their health checkups come back much improved. They are also significantly cheaper than cigarettes.
One woman I know has stopped smoking and uses the nicotine gum when she feels she needs whatever it is that nicotine does for her. It helps her not go back to cigarettes.
Perhaps instead of coming at her with anger, you could try to help her. My suggestion is that you get her a good ecig. Get liquid that is made in the USA or the UK. The liquid comes in different strengths and flavors. So she slowly cut down on the liquid. There is most likely a place smoke shop near where you live.
The idea of this is many fold
1. Bring it out in the open more than it is. Remover what she perceives as her need to hide her addiction.
2. Itís a lot easier to solve a problem if itís out in the open.
3. It turns you into her supporter for quitting instead of the person who she wants to please but keeps failing.
