Needing advise from an outsiders prospective?

Long story short! Me and my partner we have been together now for 3 years, we both used to be on drugs, we both ended up in jail, now we are out and completely clean. All he does now is lay on the couch, watching TV, now I can't just sit at home all day, all week, constantly. I have 1 friend and when I can't take sitting at home I go see her for a few hours, sadly she is a drug user/smoker, When I come home why is he so sure I am on drugs? To the point I have no friends now I can't go anywhere by myself because I'm an apparent druggo, he literally told me not to come home!! I have tried reassuring him I'm clean, I have even offered to do drug tests for him but he dosnt listen, when he makes accusations that's it nothing else is true.
