My boyfriend is 17 and he has tried hookah once... tried brown sugar once.. he used to smoke cigg and drink on occasions.. I said I can't be with him?

I said i can't he with him and he promised he'll leave all those.. He said he tried that because he was living in hostels away from his home and now he's home again so he'll never try again and said me to sty with him.. Bt I don't know I'm not feeling safe now after knowing these all.. Am I overreacting? Or am. I wrong if I'm leaving him or should I stay with him coz he's Appolozing so muchh πŸ™‚ I don't know I'm confused as hell
