It's nightmarish seeing forumers advising Andrew to "treat her
like a wh*re first then dump her", "f*ck her more while you can",
"vent your frustration", "take pictures and videos of the whole s*x
things'', "shoot inside her and impregnant her" among a list of
other demeaning acts.
I don't think there is a need for you to perform thorough planning
for sweet revenge either. It's simply a natural phase in life, time
and chance; the both of you having once been irrational and in love
until the moment you decide part.
IMHO, futile for you to take revenge. Save the drama for prime time
soap opera act. Things are simple as it is. If you want her, then
continue. If you're ultimately selfish and you love yourself more
than you do for her, then just leave. I don't know you in person
but being a man isn't defined by the number of pussies you've
scorned or kissed (save that for the kids). It's measured by how
far you will go in providing for your woman in return for the
comfort she gives you.
Everyone and everything comes and goes, they live and die. Some
things in life simply don't need an answer, you just need to walk
on and not look back. Some people are good for the past and rotten
for the future.
What matters now is you are current and you are living.
And in every facet of your life, never forgive betrayal.
Never.
