Mmmmm... I mean - I am in a relationship where I am the breadwinner. My partner is currently incarcerated. I make way more money than he ever did.
So in that sense, I am the leader.
That said, my partner takes care of me emotionally. He lifts me up whenever I am down. He helps me realise my true potential. He's my best friend, and my soulmate. And when he's free, we will work together to achieve our dreams.
But that doesn't mean that I am going to subsume my own dreams to follow his dreams. It's more - we have shared dreams. So I'm not "following his lead", we consult with each other for what we want. And we also both have individual dreams that are not shared, which we can help each other with, but also require some independence.
Don't assume that all women want a "leader". I respect many men in my life, I have brothers, a father, many male friends - as well as my partner. I have male colleagues. I respect all of them as intelligent, driven and capable individuals. None of them are my "leader". I don't need to see anyone as "above" me in order to respect them. That's laughable. We are equals. We have different vulnerabilities we need help with. We can lean on each other in different ways.
The idea that the man in a relationship needs to be the unilateral leader is regressive. Every couple is different.
