Need someone to Vent to.

So I am 23 weeks pregnant. yey for me. My boyfriend started to smoke again because his Vape kept messing up. I recently learned about the health hazards of being near the ciggarete smoke even if it's just a faint smell of the breeze or even someone else in the apartment building. Even the risks of it left on clothing. I recently changed the bed sheets and the man's going fishing tomorrow, perfectly fine. He goes out to smoke and I nicely tell him if he could change his clothing on the way in and wash his hands.

He quickly gives me this

Have you lost your mind? what idiot told you that.

I have a home nurse I got a part of a really cool program for my pregnancy and I'm just destroyed he's not supportive in any way of her..i just don't know how to kindly share some facts about the hazards. I just don't have anyone to go to or talk about issues like this.
