Yes, eventually I left. Life is too short to spend it with someone you don't love or trust and I wanted better than to spend my days in a loveless marriage, so I left. It was a difficult decision, but ultimately I was able to find a better "partner in crime" as I affectionately call him. I have total trust and love for my current partner, and had I not removed myself from my first marriage, I would not have found him.
Sometimes love isn't enough - there has to be respect as well, and I cannot respect someone who would violate my trust.
