My wife has been exhibiting dillusional behaviours which has severely affected our marriage. Her condition got worse soon after she had our second child. She began to withdraw from her friends, accusing them without proof. She hears voices and talks to the dressing mirror. She says that I have conspired with other people to make her nakedness and personal life visible to the public. She no longer answers phone calls. She has stopped talking to her mum and family, accusing them of being complicit in her current predicament. She locks herself indoors, and has severe OCD. She wont let the kids socialise with other kids, apart from taking them to school. Friends no longer visit us for fear of suffering embarrasments. She kicked me out of our bedroom over 4yrs ago, and we havent been intimate since. In her daily rants, she says the step dad abused her, and the mom discriminated against her. People she trusted took advantage of her vulnerable situation and molested her, getting her to perform sexual acts against her will. The GP and mental health experts have admitted that she is dillusional but they'll not intervene until she admits that she has a mental health problem. Her condition is getting worse, and I fear that my children will be affected. I'm going round in circles. She refused to comply or see a doctor when i sent her and the children to our home country for treatment. What other avenues can I explore, how do I cope with this situation?
