If it works or not is dependent on each particular situation. But I think it’s always the best course when your ex doesn’t want to talk to you, or else you can make things worse. I can tell you from my own experience. I know how difficult it os to keep NC, but you have to be strong and stick on it. Today is my 21st day of NC and I am proud of it. The dumper has all the power until they realize that they don’t posess you either, and then they eill come back or move on
