This is blatantly art of seduction in full swing.
I always believe that most men will lose, both heads, against a
professional Siren because most man doesn't know how to handle a
Siren, more than her leading you by your nose in this carefully
crafted seduction spell that render you immobilised and awe by the
power of fantasy, visual and sensuality.
When you sealed tight lips about your bona fide gf in Singapore,
your subconscious have already decided to cheat.
You allowed your soul to accept the consequence of infidelity. This
is a choice you have chosen - to be a promiscuous man.
Whatever story that she has weaved (authentic or not), seemed to
compensate your ego of having to be a woman of fantasy, equipped
with a sad tale... and only you are fit enough to be her knight in
shining armour and release her from hell. In return, you are
bestowed with a woman looking like model and a body like a coke
bottle - submissive and attentive to your physical and emotional
needs.
In fact, this is a fantasy you once thought of in the past, coming
to reality.
You are in love with a fantasy, blinded by this hedonistic aura of
light that keeps you bounded by her, which transcend distance.
Singapore? No problem. Aussie? No problem. AOS speaks of its sixth
strategy - the art of insinuation and CloUdiSm speaks about the
theory of omnipresence; your mind is dominated and that is
sufficient.
You must understand that you went overseas with vulnerability and
emotional void. You are a perfect victim for woman like her because
she seeks an isolated man like yourself, overseas with long,
drudgery relationship back home. Like a chameleon; she could adapt
and change into something that fits you nicely, something which you
long for, but isn't substantial.
If you wish to turn this piece of fantasy into reality, you will
probably be horrified by how hasty your fantasy crumbles, which
will reveal a certain insidious reality about her and the
consequence of having a relationship. Vice versa to her; you are a
probably fantasy to her and if she were to know the truth, your
image crumbles and reduced to that of her previous boyfriends -
should all her story be the truth. You are unwilling to let that
happen, which is the reason why you are not being truthful in the
first place.
If you have a problem in your relationship, you don't avoid - you
solve them. You introduce a third party, you complicate matters. If
you have the courage to cheat, I don't see why you can't use the
same courage to face the problems in your relationship. In fact,
you probably need more to cheat than to face your BGR issues.
You ended your post with 'I am a jerk' - what are you trying to
prove? Which also implied, what is this topic for? For others to
hurl abusive words at you? So probably you can feel better? I
supposed you have accepted this mess that you have inevitably
created, as an integrated part of life, which probably hinted that
you would go along with the destiny you have craved for yourself,
by telling yourself you prefer thai girls than Singaporean
ones.
Then go along with the thai girl and see where this choice will
bring you. I don't think you are looking for advice more than a
channel to release some guilt in you via words. 
Cheers
