Mad about husband starting again after quitting

Husband and I have been together 10 years and married 8. We have no kids.

About a year after we got married my husband started using marijuana as a way to help his depression and keep his stress under control. He usually only smoked in the evenings after work as a way to wind down so I was ok with it. As time when on and when he started working at home during covid the smoking got more and more intense to the point where if he wasn’t smoking every 45 minutes he was absolutely awful to be around and I was always the enemy. Then he would smoke again and apologize. I’m embarrassed to admit this but I would be on him about keeping on top of his smoking just so he was nice to me.

About three months ago he decided he wanted a different job so he quit cold turkey. He never mentioned quitting to me but his mood change told me it had happened. He denied it for a week until he admitted it. The month after he was quit was an absolute nightmare. He was absolutely awful to be around and live with. The timing was also awful because I was recovering from surgery. He actually quit the day before I came home from the hospital. The day I came home he told me he wanted a divorce and he couldn’t handle my laziness because I was 24 hours post surgery and couldn’t stand up and make him dinner. He spent days at a time in bed saying he hated his life and wished he had never married me. I ended up going to stay with my best friend because I couldn’t handle his tirades anymore. Two weeks after I left he called me to apologize and I came back on a trial basis. He as better but still mopey and very quick to anger and irritation.

We’re now three months out and he has finally leveled out. He’s happy now more than he is upset which a huge win and our relationship is slowly recovering. Today was his first day at his new job. He came home and told me since he now has the new job he’s going back to smoking again. This terrified me because the thy thought of him randomly quitting again once he starts and us having to go through that saga again sounds truly awful. I told him I didn’t think he should because he’s finally in an ok place without it. His response was “do you want me coming home from work everyday and ripping you a new one then?”. I’m

floored. I left the house and went to the grocery store and came home and he already had bought more (we live in a legal state) and was smoking again. I’m heartbroken. Do I have a right to be upset about this or not since he’s a grown adult? Opinions would be great.
