Trust is a funny thing. In a way it's blind, and deaf, and dumb! But in another way it is totally fragile and once damaged, soooo hard to repair. Broken trust calls into question your own ability to know another person. All your previously formed opinions of that person are now called into question. Everything they say or do is now suspect.
Sadly, I'm not sure that any broken trust relationship will ever be the same. Healed, yes, but forever scared.
