One of my closest friends is an ENFP. There is a side of her behavior that puzzles me.
This ENFP is very beautiful. She was a model for a top agency at one point in her life. She certainly gets a lot of attention. She always has an orbit of admirers around.
On certain occasions where I'm getting more attention than her (it doesn't happen often) she becomes either withdrawn or possessive. My ENTJ friend even noticed this and asked me about it. It's something that I noticed myself but never said anything about.
Some examples: I never get dressed up or wear makeup that much. People don't recognize me when I do. On my birthday, I decided to pretty it up and sure enough got a lot of attention. ENFP was complimentary toward me then kept mentioning that she thought she didn't look good enough that night.
Another time, we were both at a bar watching live music at a table when this woman approached and started hitting on me. ENFP reaches over and lays her hand on my thigh in front of the woman. When the woman leaves she goes back to 'normal'
When she first met my ENTJ friend, she actually physically pushed the ENTJ away from me when we were at a club dancing. We were all drinking but I was shocked that she would do that.
Me and ENFP dated very briefly about two years ago and streamlined into a close friendship. I know ENFP doesn't like me in that way so I can't understand her behavior.
