You are right .
As far as power differential no we don't do that ,a mutually beneficial relationship is a partnership that you both equally contribute to and work at ( doesn't matter how much money ,or property or any that rot you contribute) when my late wife and I married , we wrote our own vows ,and neither of us wanted any part of obey ,that's a power differential right there neither of us wanted that in our relationship , love and honor are fine (I have a very unflexible personal honor code instilled by my mother ,my wife always new I would make good decisions because that's how I am wired)

Anybody who ties there self worth into another person's "love" is going to have a series of crisis over and over everytime a relationship ends , until they see the light they will never find what they are looking for and will plunge from high to low with each failed relationship, never rebuilding themselves without some proffesional help ,honestly you have to love yourself before someone else truly can or will.
