Detachment is neither kind or unkind. It does not imply judgement or condemnation of the person or situation from which we are detaching. Separating ourselves from the adverse effects of another person's alcoholism (I replace it with cheating) can be a means of detaching: this does not necessarily require physical separations. Detachment can help us look at our sitch realistically and objectively.
Detachment allows us to let go of our obsession with another's behavior and begin to lead happier and more manageable lives, lives iwth dignity and rights, lives guided by a Power greater than ourselves. We can still love the person without liking the behavior.
