Thanks all for helping me to think more rationally. 
With all ur help and suggestions, I think its easier for me now to
not cross that line (at least for this moment). I am 24 this year,
and never had a gf in my life so far, so I'm still pretty green abt
BGR stuffs... But I do know that a good potential r/ship stems from
a good solid friendship. For this instance, I'm pretty happy the
way things are going, so think I'll just let it be.
And yes, Master hit the nail on the head.. *kowtows*
You knew what was going inside my head. More often than not, its
always this tot of "should i go out with an attached girl" .. u
know as some guys would say "why place ur stakes on this one when
there are others out there ?" ... I personally find she's a
sensible lady, and a worthy good friend to keep. Thus, all i seek
is her friendship at the very minimum.
No one can see the future I guess, so its all up to me to make
myself a better person.. both in character and in career

And btw, I tot my nick was kinda funny.. since i had a friend who
often 'abused' that phrase.. haha 
Once again folks.. for all the advice and enlightenment you all
have given me.. I thank you
