I'm sorry your boyfriend is not being more sensitive to your fragile quit situation but your quit is for YOU, not him or anyone else. You alone are accountable for how your quit turns out. You alone took that cigarette, put it in your mouth lit it on fire and took 2 puffs. No one else made you do that. You know that you can't take even one puff without putting yourself right back to the start of your quit. So now you need to start over again. What will you do differently the next time a similar situation arises? You need to have a plan or you will end up with the same result.
I'm sorry if this sounds harsh but it's reality. You had studied this addiction well and had planned your quit well and done all the things you needed to do in the first 2 days or so. Now you have had a major setback - yes, 2 even 1 puff is a major setback. How will you deal with that? I sincerely hope you find it within yourself to make a new and even stronger commitment to quit. Quit for YOU! You deserve a healthier, happier life!
I understand relationships in life are important too, of course they are but so is your health and your future health. I really hope you do not end up feeling you have to choose between the two. Maybe you can talk with your boyfriend once things settle down a little. Let him know how important quitting is to you. If he truly loves and respects you, he will do whatever he has to in support of you. I wish you well Kellemae . I know you can quit permanently if you make it the top priority in your life :)
