Is there an "inner"personality as well as "outer"personality? Is it possible a person with good "outer" personality is missing inner personality?

Is this same as introverted vs extroverted?

To be more specific I'm in a relationship for over 20 years and outwardly she is fine, perfect in fact, but in close moments together there is nothing. Over past 20 years we have developed zero closeness/ observations/in jokes

I hope this makes sense

And i suspect it's unusual a guy writing this about his wife rather than vice versa
