the question is, why do you suddenly feel a need to
apologise?
oh u realise that she might be a potential target now(assuming
that you are single), so you might wana trigger some sparks back on
her?
there is nothing to say sorry abt, esp when it happened so many
years ago, unless you did something terribly wrong.
such a long time has passed, and i think she has moved on in her
life long ago…
