My boyfriend and I have been together for almost a year now and when we first started dating he smoked weed all the time. I never liked it and wanted him to stop. About halfway through our relationship we broke up for a few weeks and he came back to me saying he stopped smoking and wants me back. We've been doing so well in our relationship and he recently brought it back up that he wants to start smoking again and thinks it's dumb that I'm not okay with it. I really need some advice
