My boyfriend doesn’t want to quit..🙄

My boyfriend joined the army at 18. He’s now 26 and has been smoking cigarettes since he joined. When he came home after I had our first I started smoking but I quit a little over a year ago. I’m now pregnant with our second and HE NEEDS TO QUIT. It smells horrible. I hate that I can’t lay on him at night cause he HAS to have his cigarette. He has no desire to quit. His excuse is I smoke when I’m bored. There’s plenty he can do when he’s bored. He refused to take chantax or use the patches or gum. He claims he can quit on his own but he can’t. Either that or he hasn’t really tried. Any advice you ladies have ?
