i believe it is hard to maintein a friendship which is no
"pure"
can one really be tat rational to differentiate bet the past and
now?
even duo the fact is tat u are friends now, however there was once
tat u are so close to him/her and u will tend to treat him/her
beyond friendship if u still have tat "feeling".
finally there is an ego factor as both of u were once together
(perhaps) so wat he/she do now somehow links (actually not) both of
u together.
u will not be happy to see her with someone who is worst off then
u.
u might think tat "wa liao, her taste so bad, even such guy can get
her and y did we end up this way and might start to
compare...
I believe it is due from case to case basis, but how many really
have treat their ex or the gers they courted as friends.
unless they can live in the face of disappointment, failures and
"face" factor.
