Considering that men comprise fully half of the individuals who get divorced, isn't it reasonable to expect they would at least be a significant presence in the divorce discourse?
In my role as a mother turned amateur anthropologist, I've been shocked at what I did not know, horrified at what I can't begin to understand and terrified that I'm not up the task of raising creatures who leave laundry strewn about the house.
I never met a man who was so satisfied with his lack of emotional control that he refused to accept that change was possible. The problem is learning how to deal with their feelings when they arise.
You would like your Boomer husband or boyfriend to open up more and talk about his emotions. He's probably aware of his feelings; he just hasn't said them out loud very often.
Men don't talk because the very vocabulary for day-to-day life has been so dominated by a female frame of reference that we've lost the ability to explain ourselves in any meaningful way.
