Our entire network of female friendships comes from speech, and this is even truer today, in our busy lives, where the phone is probably our main tool of communication. The shock and pain that these women experience shows how much of their identity was defined by the relationship, not themselves. But typically, men act more than they talk. But there comes a time when the boy grows up and moves away from the mother's talk to play with the boys. For men, talking about love is meaningless.
Love has to be shown through actions.
And they think their girlfriends feel the same way, and so are sincerely surprised to find the opposite to be true. The shock and pain that they experience shows how much of their identity was defined by the relationship, not themselves. It could be said that situations like this happen more easily with men and women who aren't completely secure in their own personality. In the past century, women, by showing their masculine side, transformed themselves economically without abandoning their feminine side, that is, their roles as lovers and mothers. I think that women now expect men to let out their feminine side and to express themselves.
