Boyfriend smoking more!

Jessica • Finally Due In June!!!

So the second we found out i was pregnant, 2 weeks ago. I stopped smoking pretty much immeditely, i got myself a vape because i figured that would be better for Squish. However now im not smoking the vape as it made me want to throw up. However my boyfriend has started more, and more to the point where tonight ive just taken myself off to bed in tears. He doesnt really get it i dont think as to why im upset, but i cant stand the smell, and hes doing it so often around me its like he doing give a damn about the hard work im doing right now!

Anyone no how to approach without being a blubbering mess?!
