I'm sorry you've been through such a painful experience. I was married to a narcissist for thirty years, and am glad we are no longer together. Yes, he moved on quickly, which narcissist's tend to do. But not all narcissists are the same. There is a wide spectrum, and I am choosing to believe that he genuinely loves and is committed to his new wife, even though it causes me more pain to think he could do this with someone else when he could not feel those same things for me. Maybe I'm naive, but I hope it's true.
