To me, whether you wanna give up or not, isn't
exactly the greatest concern here. I feel there is something more
critical here that you probably have to learn about your failure
before history repeats itself and you find yourself experiencing a
double whammy.
This is a case where you rejected yourself.
...how can a poor guy like me give her happliness. So i
try to keep distance away from her, dont call her, reject her call,
and even when i saw her i just say hi and walk off le
After that she didnt call me again le, and i also didnt
want to interfere with their relationship problems.
If she is attached, whether or not to give up, it
remains subjective to the individual. You chose to give up, its
fine as well. BUT the above malicious mindsets will serve to ruin
you until you decide to do something about it. Happiness talks
nothing about monetary wealth dude - only people who doesn't
understand thinks that its all about money. YOU haven't even
started and killed yourself with this thought - very bad.
IMHO, when you two had almost zero contact and she called you out
of the blue and related matters of the heart - THIS IS IN FACT,
blatantly a fringing` obvious hint that she is trying to drop.
Reasons' very simple: when your emotions is in the mess, you scan
for the closest/intimate companion in your memory to rant or talk
about it. Your love affairs is such that people usually can't talk
very much to others they ain't comfortable with, because it
involves the next stage of emotions - opening up. You don't find
strangers/hi-bye friends, whom you do not have contact for so long,
to talk about these things UNLESS your scenario causes your world
to shake and all closest/intimate friends became an unsuitable
channel. (Or unless you are a known AA to your friends)
She calls you because unconsciously, she wants you to know that she
is single. Duh, obviously she knows that you probably had some
feelings for her.
P.S: This is a
case of self-rejection, not rejected rejection.
