Husband suffering from schizophrenia

I am married for 18 years and have two children aged 16 and 14. My husband was a wonderful jolly loving person. He faced many business stresses and traumas like robbery and assault. The last 5 years has been a roller coaster living with him. The psychiatrist said he has bipolar schizophrenia with lots of paranoia and hallucinations. He refuses to take the antipsychotic meds ability and is making our home environment hell. If you look at him he looks like a good moulana. White kurta and mashaallah beard. He is always moody sulky and paranoid. He only makes salaam to me and thats it. Please advise how do I live with this silent treatment for years and the pain of emotional abuse. I am sad heartbroken and emotionally drained. I am staying for the sake of my children.. is there any support in Pretoria for women who are being tortured by selfish husbands like mine. His illness has robbed my of my happiness. Please help me understand why he does not want to take meds to get better.
