How can I stop him from doing weed?

Thank youu :), I dont want to change him, but I dont want him to harm his body and be stupid enough to actually do it in the first place. I am thinking about ending the relationship because I dont want to get involved with all that stuff and I dont want a boyfriend who is involved with all of that too. thank youu for the advice:))) xxx

just tell him you dont want him 2 get hurt, and if he wants 2 calm down just 2 call u. thats what I tell my boyfriend. he likes 2 do week, pot and all that crap, but just tell him if he really loves you he will stop and stop 4 good, because everytime you c him do it you cry and cry because you dont want anythin bad happenin 2 him. and remond him if he does it then he can die from cancer, remind him you love him and that you would love him even more if he stopped. I did that and my boyfriend hasnt done weed or pot in at least 2 years now. good luck!!<3

it’s hard to do that, just leave him it’ll be way eassyer for the both of you.
