dont noe how to answer yr question...
But at least, I can say the dynamics of a person's
emotions...
Assuming when both of them are not together and no longer with each
other, both of them are emotionally hurt....
Then subconciously his or her mind will go into a defensive mode
where it will prevent him or her self from entering mental
breakdown stage... And subconciously, the emotions (could be love
or hate or blah) will decrease with respect to time... But still,
the emotions for one will still be there when one has reached to
his or her last stage of life 
the only thing is
"how much???"
Different people have different curves ( amount of emotions against
time)... Some people exponentially decrease after very short
time... Some people decay very slowly even after a long
time...
It really depends lor...
Ok... if u still dont understand, then there r 2 morale of the
story is :-
1) If u really want, dont wait ... the longer u wait, the more it
unfavours u
2) If u really dont want, then dont wait... Carry on with yr
life..
