We’ve been together 3 years, living together for 1. It all started with me trying to have what I find to be an important conversation with him about how I wanna smoke less weed (we are both smokers) because when I do too much I get anxious. Telling him this did not get the reaction I thought it would. I thought he would be more supportive, but he just sighed and wouldn’t look me in the eyes for a minute, looking upset. He told me “it always starts with this” and how one day, I’m going to try and impose my views on him about smoking and try to force him to stop. I kept explaining to him that no, I don’t wanna make him stop smoking, but he just kept going on and on about how “all his previous girlfriends and some of his old friends did the same thing”. I kept trying to reassure him, but it didn’t work. He said he doesn’t believe me when I tell him that I don’t plan to do anything like that to him. The conversation has left me feeling a bit hurt, like he doesn’t have trust in me. Any advice for how I can communicate this to him without upsetting him again? I’m not sure what to do now.
