I am slightly biased as I did trust my partner completely in a very naive way, and then it turned out that he had been cheating on me for 15 years - and with several of our joint friends. It was the biggest shock of my life, he had deceived me so thoroughly all that time. I haven’t viewed the world / relationships as being safe ever since.
I read threads on here about women whose partners turn from being a perfect family man into a cold stranger (due to OW coming into their lives). I also read threads from women who consider their partners to be their best friends and have good trusting relationships.
One day I would like to be again in a relationship - with someone I can actually trust this time. So my question is how do you when can trust your partner - or should you actually ever completely trust your partner?
