Do you really care?
Women often don’t know what they want. As a man your job is to just live your life. If a girl doesn’t want to be with you anymore then that’s just her jumping off of your ship and diving into the ocean. Not her getting her own ship. This is not power, but the illusion of power. You could say she’s jumping to another guy’s ship, but even that captain will know that she’s just a fish that truly belongs in the ocean... hopefully.
You, as a captain, as a man, just need to keep steering into the sunset. This is your adventure. Women are members of the cast.
