Making you question trust even if it's just going from 100% trust to 99% trust is becoming more paranoid. Thus permanent damage. Also why would you understand someone being a wise and beautiful woman?
This is an absolutely silly oversimplification. Trust isn't broken up into percentages, it's a human emotion that is far more complex than you're making it out to be. I don't know about you, but I don't have an overall "Trust Meter" the shows a percentage of my "trustability." Every situation is different, and warrants varying levels of trust. Once in a serious relationship, there must be trust, so we'll say, for your oversimplifying purposes, that once the relationship becomes serious I trust Girl A 100%. She then cheats, yes, the trust in that relationship is broken, and often why the relationship must end. However, if I start dating Girl B, and get serious again, trust in that relationship is back to 100%. Getting hurt the first time doesn't decrease my emotional ability to trust universally. If you're trying to claim it does, then you need some therapy, because you aren't handling the emotions properly.
Why would I understand someone being a wise and beautiful woman? Because I understand that the world isn't black and white, that motivations, desires, choices aren't clear cut. I know that good people can do bad things, and bad people can do good things. I think cheating on a significant other is an absolutely terrible thing that is done, however, I understand that it happens, and even good people slip up. Honestly, it sounds like you've got a bit of splitting type cognitive distortion. Of course, I say this over the Internet and with no solid diagnostic evidence aside from the few things you're posting here, so take it with a grain of salt.
