what should I do ?

this isn’t your typical tmi question it’s for my ladies in relationships, & smokers !!! I need some advice gals , on my mans and his smoking habits. weed. not cigs. sooooo I don’t have an issue with him smoking but I just wish he wouldn’t do it sooooo much. I just don’t like it when he’s high all the time. he smokes a lot and I don’t like it at first I asked him to quit but he didn’t want to so then I said can you just not do it all the time then ? but he still doesn’t want to and it frustrates me so much what should I do ??? he tells me he understands if I feel like it’s a deal breaker but I don’t want him to understand I want him to limit himself or just quit !!!
