Chameleons

Are Ns like chameleons. Do they just morph into different personas at different points in their lives? My STBXNH always talked about the different times of his life as his different personas. The country boy, the city boy, the corporate man, the ect. He "becomes" these different people, and the people in his life at the time support these different personas, or are parts of these personas until he morphs into someone else. The GFs play a role in each of these personas. Has anybody else experienced this behavior? Do your exNs describe their lives in this manner? I was part of the "family man" persona. Where is the core of these people? It is so abscent. It is like they were costumes and have props. I know there is a core in there, but it is buried so deep, or it is so lost. I am just curious if this is a common description.
