We all do ultimately find or make our own closure for any unresolved situation in our lives... I'm not sure where the idea came from that we're meant to seek "closure" or resolution in a dynamic wiht another person from that other person. Even with dialogue, we're the ones who find our resolution. Blocking another person is fitting advice if the person you're "moving on from" is a pathological parasitic predator and even perhaps a person with self-focused narcissistic glitches. This article doesn't mention this. - Though it's against our natural feelings to cut someone from our life, it's a necessary life preserving technique to use to escape the predatory and avoid the dysfunctionally narcissistic. While there won't come a day that it feels "good" or that it's simple and easy to go no contact from the pathological and maybe the deeply dysfunctional, it's a must. - However, if we adopt this attitude with all people across the board, the planet and humanity will be weakened and spun into a place that's the opposite of where we'd like to go. - Among fully human humans, diialogue is key.
