Lama Ole’s answer:
I only know of one good way to end a relationship so that both partners walk away enriched. We have to get used to wishing the former partner everything good all the time from the outset. If there is any win-lose thinking involved, nobody will be set free. Simply make good wishes as a matter of principle; give everything good and be really generous in sharing possessions. The only exception is if the other person is taking advantage of your generosity. In that case, negative habits would be encouraged in them, and it’s best to cut through instead.
But when two modern, talented, and humanistically minded people separate because their shared good karma is exhausted or they haven’t created new good karma together yet, then I would advise separating in such a way that both people win. Both should feel good afterwards and they should remain friends. Feelings of loss and restriction shouldn’t be connected with it, because then we carry along all the difficulties we experienced. If it has been quite a while since the relationship ended, you can wish the other everything good from a distance.
