The main problem with love is that one of the partners is often not mature enough.
If you are a mature person psychologically, spiritually, you will not fall in love with a child. A mature person has enough integrity to be alone. When a mature person gives his love - he just gives, he feels grateful that you accepted it, not vice versa. He does not expect you to be grateful for this, he does not need your gratitude. He thanks you for accepting his love.
When two mature people love each other, one of the greatest paradoxes of life occurs, one of the most beautiful phenomena: they are together, but at the same time, they are immensely alone. They are together to such an extent that they are almost one whole, but their unity does not destroy individuality - in fact, it increases it, they become more individual.
Two mature people in love help each other become freer. There is no politics, no diplomacy, no attempts to subjugate another. How can you try to subdue the person you love? Just think about it - submission is a kind of hatred, anger, hostility. How can you even think about subduing the person you love?
Their personalities don't mix - they are amplified.
