Immature love says: ‘I love you because I need you.’ Mature love says ‘I need you because I love you.’
In love the paradox occurs that two beings become one and yet remain two.
It is difficult to know at what moment love begins; it is less difficult to know that it has begun.
Henry Wadsworth Longfellow
It is sad not to love, but it is much sadder not to be able to love.
Miguel de Unamuno
