The phychological fear of losing.

In life ,whenever we get close to someone,we develop some kind of attachment towards them.You become close to them for some reason,and that reason could be anything.The waves from your brain will start resonating with the waves of the other person's waves(for that particular reason).the two waves will resonate only when there is a match in frequency and the amplitude of both the waves increases when they are together,,..And for any reason,if one of the waves start drifting from other , there 'll be a disturbance in the other. This disturbance can last for any amount of time , depending upon the type of person and also depending upon the amplitude which they reach when they are together..( Higher the amplitude, more is the disturbance)..
This phenomenon can be seen in any form of existence. It could be ur friend , with whom u could get along very well, and suddenly he/she starts ignoring you or starts spending more time with other person. This phenomenon can also be seen in mothers,whose son is getting married and she feels that his son will be controlled by her daughter-in-law and not by her anymore,she would feel so because for more than 20 years she has taken care of him and now she's losing control over him. this will lead to further tussle between mother and her daughter-in-law.
This phenomenon exists not only in human relation but also in organisation or anything for that matter. Eg, In any organisation if a very highly talented person is leaving the company,it will lead to "Fear" of losing him, and due to this distubance, the organisation will start offering him more money or promote him to higher position etc.
So, this Psychological fear of losing someone exits everywhere and the only way to overcome it is to pass through it. Feel the pain fully so that you'll totally overcome it and you will never face it again in your life.
