You mentioned that you have a problem trusting woman, yet you
are entering into a relationship with this issue within you. You
feel that going through an online relationship with a Malaysian
over a LDR wouldn't be that as well? Fear that it would fail?
Here's a truth -once you entered a relation, like condom, even the
best ones have 0.01% of failing. 
Your ex is your first love; in the first place, without her, do you
actually think you will know what you really want in a girl? Or do
you not know even now? You have difference with your ex - do you
understand that such are inevitable events in love and have you
actually realise what are the learning pointers behind the
conflicts? 
You want a good, fulfilling relationship and this requires constant
enlightenment. Nobody can enlighten you to path of a happiness
relationship - you are the only driver. Love without making too
much mistake is the goal everyone is seeking - you are of no
exception. You admit you are suspicious and possessive - you have
ever done anything to correct it? These are flaws to create cracks
in your possible love and many others, whom you never state or
never knew. 
Your current situation? LDR is difficult ball game. You met her
through internet and you said you have problem trusting woman, then
what makes you trust her? Online, overseas and preception based
purely on her words and voice? My view is that chances are, you
will triggering what you feared; futile relationship.
P.S: Again like condom, the freak cases have this 0.01% of making
it work. I am not saying that the figure above represent your hope
in maintaining this relationship with her - however, if you chose
to seek lower risk relationship, in the first place, you wouldn't
and shouldn't even have consider this proposal at all. I understand
your conscious and subconscious needs - she could be just
around.
Are you a Scorpio or a Libra?
