Marriage

I've been married going on 2 yrs. Together 3 yrs. My husband is bipolar 1 also suffers from severe depression, a yr ago he got into some legal issues and was given probation for 2 yrs. He has always smoked pot because he said it helps him with his disorders and keeps him calm but a yr ago after this legal problem nothing big . He stopped having sex with me lost 2 jobs. We would constantly argue I honestly would start to say you dont love me ur with some one else because he wasn't having sex with me. So I kept picking on him. So about a week ago we separated for 3 days I came back home . I pay rent I was the one who had to leave. I found another phone so i asked with balls according to him why do u have another phone. He got so mad he had nothing on it. So again he said I dont want u I love you but I need sanity. I'm heart broken so idk what he wants he loves me he tells me to tell him where I'm going he tells me let's see how we r from now to the income . He tells me hes testing me to see how I react I know this sounds childish but I want to know if hes doing the same thing I would do to him or is he just wanting me to realize and be good to him
