I see very subtle signs and it has scared me. We have been together for about 5-6 years, but on and off. When I met him, he started smoking (weed) more. I never realized that weed could have such terrible effects, not only on him, but on me (our relationship). I am aware now and this is why it scares me. I'm not married to him but we have spoken about this in the future. His use is a deciding factor and I've made it clear to him.
I have been getting counseling over the last year on a steady basis. This has helped me tremendously. He said he quit and made other positive changes in his life including not spending time with his friends who smoke. For the most part, I could see positive changes in his daily life. During the last week, I saw some odd things.
I don't know what else to do except see for myself what a drug test would show.
