I figured this out in therapy today but can't understand WHY I feel relief when a paranoid thought is true? 

Example: If I am paranoid that my husband has another telephone number that I don't know about, I would feel relief if I confronted him and he said "Yea, I have another phone number" vs if he said "I have no idea whose number that is." I would just feel more anxious/paranoid that I still DID NOT KNOW. 

Like the confirmation that he is doing what I'm paranoid about is such a relief.

WTF IS THIS WHY AM I THIS WAY?
