Does he have DDJ?

I discovered delusional disorder doing a search of jealousy online, attempting to understand what is happening to my loved one.

My family member believes that his wife has cheated on him. He is completely unable to let go of the conviction, even though his reasoning relies on various coincidences and events which could be otherwise explained. I am fairly certain that no cheating has occurred, and the way that he talks about his belief makes me concerned.

Some background preceding these events:

This man is extremely intelligent, well-spoken, and capable. He would not strike anyone as irrational or mentally ill. He doesn't have memory impairment or other cognitive issues.

Counseling is out of the question, as far as he is concerned. He will not go, as he sees counseling as something that's meant for crazy people.

I do not know how to support my loved one, and I don't understand what is happening with him. Is it possible that he has delusional disorder? If so, how can I support him without supporting his delusions?

Thank you for your time and any insight you might have. I am physically sick over this situation

Hi,
I'd recommend looking up you local or state NAMI chapter. They offer courses for family who are learning how to navigate having a loved one with mental illness, they also have help lines available to just talk to someone who has been through what you are going through. There is treatment if it is DDJ, the hardest thing about this condition is getting people the help they need. The sooner the condition is identified and for me the sooner I took treatment the better off I was.
Hope that helps,
Sunny

The trickiest thing with someone who suffers from DDJ and usually doesn't admit it, is to convince the person to seek psychotherapeutic help. The victim of a DDJ has no chance. However, a close trusted friend is probably in the best position to do so. I have heard, read and watched videos about this LEAP technique (“Listen-Empathize-Agree-Partner”) that can be used to encourage and motivate the DDJ to seek help but have not had the opportunity to apply it myself. It is a skill set that has to be learned but the Forum Admin would not allow me to mention the provider's name, so you'll have to do your own research. I am personally very curious to receive feedback from those who have learned and applied this technique regarding its success or effectiveness in motivating the DDJ person to seek help.
