I don't. I don't trust anyone 100%. My thinking is humans are not perfect, we are all flawed and corruptable and capable of mistakes. I think it is foolish, as an adult to completely trust or rely on another human.
I admit that due to previous experiences my thoughts may be skewed on this though. DH and I have been discussing this and he is pretty hurt that I dont 100% trust him. He argues that he has given me no reason to distrust him. He has been a loving and loyal partner for over 12 years and he deserves my trust.
I trust him as more than I trust anyone else in the world. I believe him to be a good honourable person. I am as sure as I can be that he has never and never intends to be unfaithful to me. But I am not capable of putting all my faith in someone, I have to hold something back. I am surprised this is news to him tbh, I have always been like this.
Am I weird and damaged?
