Should we really be together?
So I recently started dating someone about 3 months ago and my partner pursued me when we were getting to know each other. I noticed that were different people but, figured I'm young so why not? My partner has lived his life the way he wanted. He experimented with drugs and continues to smoke pot at least once a day. I am the complete opposite and hate his habit of smoking. It is enough to make me extremely anxious whenever every other story of his begins with "once when my friends and I were high". I've expressed to him how I feel and he said he understood but, doesn't think it is a big deal. I, on the other hand, do. I have brought this up to him more than once and he just doesn't understand. At times he brings up the future of us possibly be living together and that I'd have to get used to the idea that he will be smoking. But, that's not what I want for my future. It pains me to feel that there is already an expiration date marked on our relationship. Most of the time we tend to see intimate relationships as not having an end (that is excluding death) and I get anxious thinking that we won't last very long. He makes me happy but just as equally makes me sad. He's expressed to me that I make him very happy and he doesn't know what he did to deserve me. Sometimes I feel he would be better off with someone that shares that kind of lifestyle and enjoys it. I feel that his feelings are sincere but, I just don't know how to get past it. I am open to honest advice on how to handle the situation or whether my relationship should continue forward.
