wow....I think you are a bit delusional Bro.....you said yourself she's leaving and you know for a fact "You'll inevitably cheat" on each other....enjoy your time together...as for the smoking thing..as long as it's just social, when she drinks< that's cool....Hell, you're in a friggin bar!!!!!! Can't be to concerned with your health if your sucking down like 300 peoples smoke for 4-5 hours a night when you go out....remember, your body is not hers...it's her choice...if you don't like it and she doesn't want to change..find someone that fits your style/likes....
