I don't agree with everything he is doing, but perhaps him "keeping you away" is---in his opinion the compassionate thing to do. Trust me, active addiction is no joke. He sounds very sick and confused. The sad reality is, many addicts can get clean for extended periods of time but can relapse. It's a long, uphill battle. Do you best to detach with love and compassion. Read up on addiction, learn the difference between helping & enabling, codependency and maybe check out an alanon or nar anon meeting. Sending you hugs.
