It's probably only
the greatest relationship to you... exclusively.
I hate to shatter this idealism, but as you are here ranting about
your stagnation and even reminiscing about the golden age of your
love life, seriously on the other side of Singapore, your ex would
be out there making merry, loving the man she chose and moving on
in life gratefully without your presence.
It's really interesting to note when people can related so much
feelings about their ex-love, when in fact, these people don't
really give a damn anymore. It's like acting and directing your own
epic movie, where you are the only audience in the theatre,
laughing and weeping at your own script.
Nobody can
instigate you to move on if that isn't part of your own free will
to do so.
P.S: Time is always never right to do right - but you can always
decide your own route in life and how you want to steer it.

Cheers
