There isn't a JW who leaves (esp if they were born ins or baptized as teens) that don't have to go through a learning curve in almost all aspects of life.
There are no failures, just lessons to be learned. And no one learns anything sitting at home waiting for life, love, and happiness to find them.
Every X-JW should spend a long period of time being single (casually dating) and forming their own strong identity, likes, dislikes and life experiences. Most leave the Org with the tendency to define themselves through their relationships with others. This is not healthy and it will destroy good relationships.
I don't know what "long time" means, but I agree with this statement in principle.
