This happened recently, but has also come up on other occasions.

For personal reasons, I don't really like being in the presence of drunk, stoned, or otherwise intoxicated individuals. I have made this clear to my SO when we began dating a while back. I told my SO how I felt about these kinds of things, among some other issues which have come up.

Recently, my SO has been wanting to smoke, knowing full well how I feel about it. I reminded them I am not comfortable with kind of stuff  which has led to a struggle in our relationship, but hopefully not an end.

AITA for, essentially, disliking and not wanting my SO to do these certain things? I know it is probably selfish (its their life, they can do what they want), but I made it full well and clear how I felt about these things long ago when we started dating. Am I in the wrong for upholding how I felt then, and how I still feel? Would it be wrong for this to be a reason for us not working out?
