I’ve never heard the terms love extrovert or love introvert but after reading your article I think they may describe myself and my ex. I’m a love extrovert and he may very well be a love introvert. I never felt loved and cherished by him. As you say, I kept banging my head against the wall trying to get what I needed from him. As I look back I wonder if love was there but he just couldn’t demonstrate it in ways that meant something to me. Thanks for sharing this info. It helps me.
