Though I cannot provide a diagnosis based upon limited information, bipolar disorder and schizophrenia seem unlikely. You have described your husband as being paranoid, accusatory and easily angered. It’s difficult to explain his behavior. If I interviewed you in person, I would want to know the following information:
- How long has he been exhibiting this behavior?
- Is it only recently that his behavior has become worse?
- Has something recently changed in his life, such as a death in the family? Loss of a job?
- Has he ever received a psychiatric diagnosis?
- Is it possible that he’s using drugs or alcohol?
- Did he recently sustain a head injury?
If his behavior represents a complete change in personality, then it is possible that he is using drugs or alcohol or it may be a sign of a neurological problem.
If he has always exhibited this type of behavior but just not as severe, then substance abuse might be to blame.
Generally speaking, without more information, it’s difficult to know what may be wrong. He should be evaluated by a medical and a mental health professional. Short of being evaluated by trained professionals, it will likely be difficult to identify what is wrong.
If he is unwilling to have an evaluation or to change his behavior, then you may want to consider temporarily moving. You should also see a therapist. A therapist could gather many more details about your relationship and his behavior and provide the necessary guidance in this situation. You did not mention whether your husband was a physical threat but given his irrational behavior, and the fact that he is easily angered, it is a concern. If you believe that he is a danger to you, then call the authorities immediately. In the meantime, see a therapist who can guide you through this difficult situation. Please take care.
