Living with a smoker

Hello folks,quit smoking now,My quit is still going well. However, a new guy from Spain has moved into our apartment and I just found out he's a smoker. I've said he can smoke on the balcony (as I used to do),stop smoking, there is just the slight concern that I will be tempted to join him. My quit has been made easier by being around non-smokers most of the time, so now this is a new challenge for me. I'm thinking I would prefer it if a non-smoker had moved in, but then with maybe 1/3 people still smoking the smokers are impossible to avoid and no excuse for me to start smoking again.Anyone got any different advice?
