You've said to not let ourselves be bound by sentimental ties of the heart, and to cast aside duty (to other adults). So how should one approach casting aside "duty" when it comes to [romantic] relationship? Isn't the idea that you're 'in it together', working as a team, etc.? Or is this a flaw in perception?
Where duty binds in relationship, is when the relationship does not inspire one, but one stays because you feel you owe the other person your commitment, your life, your caretaking.
