AITAH for wanting my husband to stop smoking weed???

hello everyone. first time posting on here, i could really use advice since im freaking out.

long story; he has a history of addiction. he threw away most of his teenage years to a point where it’s a blur for him now just being high. the only reason he stopped was because he enlisted and was forced to quit. we come from different backgrounds and unlike him, weed is not a normal thing for me. i made that pretty clear to him; when we met i’d never had alcohol, cigarettes, weed or vape. i told him i’m not into people who do that stuff but he lied about vaping and kept doing it behind my back. i knew he was but i didn’t care too much since it wasn’t in front of me. then we both smoked weed together one day (i wanted to try it for fun) and obviously it was an experiment for me.

i told him im ok with him smoking as long as he promises to be careful since i will NOT want to live with an addict. he promised he would. he has recently been openly smoking it quite regularly (not in front of me but he would be honest if he was high and i asked). it got excessive, to a point where he started doing it everyday (used to be a weekend activity). last week, i told him he needs to slow down otherwise he’s gonna ruin his life and he said he’s fine and ‘has it under control’. obviously he didn’t, since i asked him yesterday if he was high and he lied about it. he was worried i was judging him and i reassured him im not judging him at all (i was. i tried not to upset him tho). i’ve come to realize he stopped turning in his academic assignments for weeks because all he does is come home from work and get high and go to bed. he is CLEARLY not holding it back well and it’s bothering me.

icing on top would be that our sex life has taken a hit since he’s always ‘too tired’ (he works a white collar job so i cant imagine its exhausting. his schedule is 12 hour shifts, 3 days a week so he also has a lot of time off to be that tired).

i told him im hiding his weed from him for his own betterment because i dont want him spiraling and that if he’s depressed he can talk to me. he keeps insisting hes fine and that im being controlling and have no right to resort to hiding his weed. idk what to do. AITAH?
