If John James really wanted to be done and over with any contact whatsoever, it would be very very simple. Firstly the fact that he lives thousands of miles away takes care about 90% of the issue. Then... its the most simple thing in the world to change your email address and just give it to your nearest and dearest. By NOT doing that, even subconsciously, he is allowing that door to be left ajar where she can make contact with him. WHY ????
As for Josie, I actually do think its a case of .... when you do hold deep down very strong feelings for someone, regardless of what your conscious mind feels, and whats currently going on in your life man wise...... even a heated row and aggravated banter means there is contact...and to the subconsious in all of us, where all truth resides, that can be like a drink of water handed to you in the middle of the Sahara desert. Its something thats craved.
I feel its far more on her side than his obviously, and yet ...as I have said, John could take very simple steps to ensure that she cannot contact him, and yet he has not done that.
Its fascinating to follow at the moment, and really does go to show that the connection here, good, bad or indifferent was certainly unique and deeply embedded in their psyche.
