This is how it works...

When two people are involved in any kind of relationship and they see that its not a workable one, the normal course of action taken is to bring down the communication to a point where both are at the liberty of looking out for other possibilities. It becomes important for both of them not to feel tied down by the other. usually in such a situation one of them takes a firm decision who is more eager to look out. The other is reluctant to let go or is not prepared to bring it down at the same pace. The one who takes the firm decision will be in a more comfortable situation then the reluctant one and does not suffer as much as the other. The one in the comfortable situation finds another association and gets committed easily. The other suffers till a point he/she breaks down and destroys everything or becomes totally bound in his/her own world. Or takes a long long time before going back to the normal condition. It is very important that they are in touch with the other person so that it becomes easy for them to come out or at least keep them sane.
