Boyfriend of 6 years hid his vaping from me. I was pregnant when I found out. Advice?

So when I first met him, he would smoke weed, mostly with his friends, never around me. I was ok with it, as long as he did it in a different space. As we continued dating he had told me he stopped, and I believe that he did for about 3 years. Within these years we have become common law and were planning our future together (I. e. be married, travel, have kids, etc.). The pandemic hit and plans altered, work for the both of us became more stressful…. Which may explain why he started to vape. I had no idea, maybe I was too gullible or naive to notice…. or maybe just really pregnant (yes, another pandemic baby).

One day we were getting ready to leave the house and as he pulled a mask out of his pocket, the vape stick (?) fell out too. He immediately said “Oh it’s just a USB”. I guess he thought I must be an idiot…he eventually gave in and told the truth about what it actually was after I confronted him. When I asked how long he had been hiding it he said over a year, which would be before I was pregnant. I was really mad and hurt about it but I hoped he would stop before the baby arrived. He also said that he would do better, that he was sincerely sorry for lying about it. At the time I was more disappointed he couldn’t be honest with me.

Well it’s been a year since I had our baby and now I’m not sure where to go from here…
Last night we discussed the issue of communication and trust, which is when he revealed that he had also hidden smoking weed from me before his vaping habit started…sometime between the 3 years he said he had quit I suppose.

Advice?
