Man, this is going to be a weird answer. I hope it gives you some thought on the whole subject of "trusting".
Do you really trust yourself completely? Does anyone ever trust anyone including themselves utterly and fully?
One place I worked, there was a rash of comics copied and passed around. I would take a look at them and laugh or ponder their hidden meaning. Some of the jokes proved to be thought provoking for me. I don't know if that was the intention.
"Never trust anyone, not even yourself. Someday, you will fart and crap your pants."
I did trust my WH. I never trustred anyone in my life as fully as I trust him.
I have Asperger's and we tend to be trusting folk, naive and a little gullible. We don't tend to lie and we usually believe other folks are trustworthy. It hits us hard when we realise they aren't.
I was bullied at school and it was a horrific thing to realise that when the girls were nice to be and told me they wanted to be my friend, they were just lying to get me to trust them so they could go "Ha ha - you didn't really think we liked YOU, did you? Freak!"
So, even though I am gullible and trusting, I learned painfully that you can't trust everyone, and to be careful who you trust.
But in all my relationships, I never trusted anyone as much as I trusted my husband. I finally thought I'd found someone I COULD trust 100%, someone who wouldn't lie to me, who was honest and open.
Boy, did it hurt when I found out just how much bullcr@p he'd fed me to my face over the last year.
