smokinggg

my SO smokes and we've been arguing about it since day one (mostly because he's been all over the place- one day he's quitting and then he's gonna pull back from it and then he doesn't wanna quit and he bought a vape and uses that) and i quit smoking in the beginning of our relationship. i know it's hard. i want to be okay with it because i don't want to stop him from doing something if he likes it. but i hate the smell, especially since i quit- we've tried tons of alternatives and brands to try to find less-smelly ones. and i hate that whenever we go out, he has to step outside and leave the event / night out / group of friends to go smoke. i just wanna know how to get past it. i'm so annoyed about it and i just want to be okay with it but i can't help it sometimes. has anyone ever dealt with anything similar?
