Degree understand your concerns went through your details. I suggest you not to worry much. I am afraid to suggest here that your wife could be suffering from Paranoid personality disorder (PPD). It is a mental disorder characterized by paranoia and a pervasive, long-standing auspiciousness and generalized mistrust of others. Individuals with this personality disorder may be hypersensitive, easily feel slighted, and habitually relate to the world by vigilant scanning of the environment for clues or suggestions that may validate their fears or biases. Paranoid individuals are eager observers. They think they are in danger and look for signs and threats of that danger, potentially not appreciating other evidence. Best method of treatment is to consult a psychiatrist as soon as possible and start prescription medicines and then combine it with psychotherapy. If treated earlier, success rate is multifold. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
