My husband won’t stop smoking.

Okay. So we have been Ttc for about a year and a half now. I’ve been totally dedicated taking vitamins, not drinking, tracking ovulation, going to the doctor, tried basically EVERYTHING to have a baby but my husband refuses to stop,smoking pot,smoking cigarettes, and drinking to have a child with me. Don’t get me wrong he wants this too but he isn’t willing to give up anything like I have. Has anyone else ever been through anything similar? And if so how did you talk through this. He’s a grown man and will obviously make his own choices But I just don’t know what to do. I’ve asked countless times but he says he thinks we will probably just end up getting a divorce if he stops smoking because he’s,”an asshole”, when he does (his words not mine.) I would be willing to work through this transition stage with him until he got too where he was in a better mood but honestly I just thinks he doesn’t want to try. And yes we have been to a specialist and we were told he has a very very low sperm count. He refuses to do

IVF

because he says it costs too much money and iui hasn’t worked for us yet. I’m at my wits end I don’t know what to do.

Ps the only reason I have a real problem with this is because both smoking cigarettes, pot, and drinking contribute to low sperm count.. which we are already dealing with.
