I used to be an expert in separation, because of my own experience and that I have helped so many people to overcome their separation… 
When we are in a deep love relationship, after some time we exchange a part of ourselves with a part of our darling, on the energy level. This means we feel that we own our darling and this also true for our darling. LoveWe are identified and passionate with our love.
This is the cause of all our relationships problems. Identification is sorrow (Krishna). 
When we finally separate, we suffer to get our part back… and to be complete again… Without our darling we feel that we are incomplete, we miss our partner and a part of us.
This is one reason, why the separation process needs so much time. The next reason is that we are habitually connected and to change a habit is quite difficult.
We losing our face and think, what should think other people about us… we become humble, alone, we feel powerless.
The major mistake is that we blemish our darling for meaningless thinks, like that he/she had done the separation awful, that he/she had abused us. As long as we keep blemishing and complaining about our former darling, we can’t get rid of our identification with our previous partner and have to suffer much longer. 
If we just feel the separation and sorrow… after some time the pain is gone, and we are open for a new relationship.
The worldly love always has two poles, one pole is hate, anger, sadness, and sorrow; the other pole is love and joy.
So deeper the love so deeper the sorrow/hate/anger/sadness.
If we separate, then all the suppressed negative feelings surfacing, because we had them suppressed to love.
If we see it so, then the separation is a purifying process.  Afterward, we can connect again with our previous partner. Why not?
