My wife cheated, then left to pursue a relationship with her cheating partner. It lasted until he cheated on her.
I concluded that I had used bad judgment when I agreed to marry her in the first place. I had misjudged her character. I failed to realize that she had a character flaw that was not acceptable to me. We all have character flaws, but that particular flaw is one that is intolerable to me.
Less than a year after separating from my cheating wife, I became involved with my current wife. We have been together for 27 years. She has a much stronger character when it comes to being faithful.
If I had anything to learn from the experience of being cheated on, it was to use better judgment in choosing a wife.
