After a breakup allot of people, usually the dumped, still has hope it will all work out.

Or people are in pain and try to get over their ex-loved one.

No-Contact rule is a great solution for both scenarios. Even when you have hope, you doubt the outcome will be what you have been dreaming about all this time. But your also moving on.

By the time the NC rule is over, you’ll be a completely different person. Able to see what you really want, not clouded by heavy emotions like 90 days earlier.

NC makes moving on, and loosing hope better to handle.
Its not easy, most certaintly not. But its something allot of people get strength from. Which is exactly what they need in their time of pain and sorrow.
