Does he smoke around you? Youre smoking too if he does...
I used to smoke aswell as my fiancee and i quit when i found out but he still smokes(away from me of course) and it doesnt bother me, he also likes to buy a lot ofstuff for himself and i dont tell him anything because he always budgets his money so we're on top of rent and bills. Maybe if you talk to him about budgeting? A place to sleep and food to eat is way more important then a cigarette. Also has he ever tried rolling his own? Theres machines that do it for you you just need to buy tobacco and filters and it is MUCH cheaper.
My bf and i were both smokers. I quit as soon as i found out and he promised to quit by the time the baby gets here. Im due in 16 days and i havent seen him smoke a cig in a few weeks and he says he stopped smoking at work too. Im really proud of him. Its harder to quit when u dont have a reason growing inside ur belly. Maybe ur husband could agree to quit before the baby comes? I didnt want my baby around cigarettes or playing with lighters (i found my nephew with one of my brothers lighters once). But if u pressure him too much he will probly just get angry.
