This was a very enlightening article.
I'm a man, and a very happy co-parent, and recently my ex-wife (who is in her late 40s) shared that she was in the same position.
I didn't dismiss her, we are great friends, but after reading this it makes me look at it from a totally different perspective. It's not the make equivalent of losing your hair--it's a lot bigger than that.
It's not something I will ever be able to fully understand, but your article was an eye opener.
