Please help me... well, I want to kill someone...

What will you do with a man that CHASE OFF YOUR GIRL? seriously... I have a girlfriend... but then, since a month ago, another man appears (he was her workmate), and start flirting out with her... obviously... start sending flowers, chocolates, and even regularly call her to check where is she...

for a little background, I was still studying my magistrate degree in another province, and she was allready working (and she was older than me little more than one year).

We have a long distance relationship, but I often going visit my hometown, and everything goes fine, until that filthy man appears!!! Apparently, all was started when that man start to love my girl... (they are workmate btw), and it looks like that she was at first avoiding him... but he was "working really hard to get her" and she was apparently start to give him some replies...

When last week I going back to my hometown after hearing about that (from my other friend!) I start to investigate about him, and this matter, he was 5 year older than me, and he was her senior (my girl just get a job).

And as you can expect, I try to speak with him... but what response did I get was really a hostile one, first, as I didn't know about him, I try to introduce myself. But when I joke arround and say that "she was my girlfriend" he start to going hostile with me, and when I ask about why he chase my girl...

HE SAY THAT I DIDN'T MARRY HER YET AND HE WAS FREE TO TRY WIN HER HEART! WHAT THE
(actually more talk is involved... but you know.... )

Oh... .... and he start to prepare to ready for a fight... (yes, a real fight in front of the office)...
And I say that I didn't want to get any trouble, and start to walk out of the trouble... he grab my collar, and try to hit my head, but I dodged before he hit me, I grab his neck and slam his head against the wall.... (I'm quite used for brawling when in Junior high, and I still had some reflex)

Luckily, before the fight was escalated... the securities start to hold us, and told both of us to leave...


And now, my brain was boiled.... he really want to get a trouble with me... but on the other hand, getting a fight in this "modern" wolrd, can result in big trouble.... as if I was lucky, maybe I can just walk out after that fight, but if unlucky enough, I can end up in a police station.....

So I try to douse my boiling brain, here, when I back to bandung again, with playing M2TW... but looking at those shiny knights made me remember about medieval ethics, that if you got some problem on your head, a combat will give you a really fine place to relase your anger.... and it just get worse.... I then open EB and still remember about it.... AAARRRGGGHHHHH

I then ask a friend and he says that I should douse that with beer... and forget that girl.... damn...
I ask another, and he said that I should get the answer in the Bible...

Well, I need your advice about my problem... what should I do....
