I haven't read the entire thread so hope this isn't now OT...my ENFP (female) best friend can be like this when she feels insecure. She can get very strange about the men in my life, almost as if they are robbing her of time we could have spent together (which tbh they are...). She can also be a bit odd at times when we're with other friends, where she'll start showing off like a 5yo to make sure she's got more attention from them than I have.

It's a real shame as she's amazing otherwise and I love her to bits.
