You're welcome! Yes, narcissists are highly manipulative. The reason others can't see this man for what he is, is that narcissists are good at charming others.
I'll give you a brief example. My mother was a narcissist who would tell friends and relatives that her kids and husband treated her badly. She had them convinced that no one helped her around the house, that we were all lazy, uncaring people. Nothing could be further from the truth. Oftentimes, her friends and our relatives would read us kids the riot act. When we would try to explain what was really going on, they never believed us. As a kid, when it's the parent who is the narcissist, you have no choice but to be around the parent. However, as we go through life and should we encounter a narcissist, we have the choice to walk away and not get entangled.
Believe me, I understand your frustration as to why others can't see through this man. However, as I mentioned previously, you have to look out for your own well-being. I wish you all the best.
