Yes, I find that fascinating! Beautiful. My husband is a INTJ and I love it! It's my exact opposite and we work together beautifully. I find it so fascinating how he doesn't seem to need interaction from others very much. I envy it sometimes. He is so content to be on his own or just with me, as his best friend and wife. As an ENFP myself (although we are the most "introvert" of the "extroverts") I'm driven to connect with others and spend time with others because that's where I get my energy from. So my husband and I compromise together and find a happy medium
It's really healthy for both of us. I expand his horizons and he, in turn, makes me feel secure and stable.
