Hi... Please visit a Psychiatrist, with or without him. He is probably going though a psychotic episode and it's not wise to suggest something based on an online query. Here, I can tell you that his problem has a solution and the psychiatrist will guide you well.
Next Steps
Consult a Psychiatrist first and a Psychologist later for Counselling.
