G.B.
When my husband and I got married I moved to a new town. I left all my friends and hubby is very much an introvert.
I ran up the phone bill hundreds of dollars talking to my friends, both guys and girls, in my old town. Plus calling my family and daughter that lived with her dad.
He couldn't fathom why I needed to spend that much money on long distance. I tried to explain it to him but just didn't have the words.
Some time later we were going to a marriage class and my hubby brought up the huge amount of money we had spent on long distance, even though I was getting better, and why did "I" need that.
The therapist said this "Do you want her to talk to you that much or would you rather she talked to them that much"? Hubby was like "Talk to them, talk to them". He never said anything about the phone bill again.
When unlimited long distance came along we got that and life was better.
Women are talkers by nature. We need speech and verbal skills to teach our children so we're more likely to have a natural need to talk and share and listen and talk and go over what's going on in our lives again and again. While we're talking we hear our words and our brain solves that problem a lot of the time.
So women need a best friend so they have someone to talk to and share everything with. Hubby's are not meant for this.
Although some personalities are opposite than this ideal it's pretty much what the difference in the genders is all about. Men are programmed to be hunters and quiet and women are programmed to share and help each other and find solutions to problems by talking about them with other women.
