You were the fool, for leaving the game before it had finished! I doubt it was any deliberate 'trick' by your opponent.
I was fooled

Whatever works, works. Some people find winning more important than honor, and you just met one of them. Never trust anyone.

i always insist on my opponent resigning first before we talk. If i am losing, i wouldn't be in a mood to chat :)

lol. you was fool.
is your avatar the janitor from Scrubs? i love that show :)
I just downloaded first 2 seasons, and watched both of them in 1 day.
You seem unhappy. I like that - The janitor!
Thing is, we just started talking about game, and I did not pay any attention if he actually resigned. I just, presumed that he did. Well, was I wrong.

Interesting you had the last move... Sou to win your opponent had to drag you out of Live Chess... Did he invited you to Meebo? Well to chat in Meebo someone must be your friend... Did he asked to you to accept his friend invitation recently sent? If so, so he fooled you... And of course dear Nemanja... you were so fool...

Fortunately, being a fool is a very temporary thing. So, since you learned from this experience, you were a fool, but you won't be anymore!
Game on!

At least it's what is expected... Anyway... Uh! You know... If you want to get fooled again just invite me for a game... It will be my pleasure to fool you one more time... ;-)

If I'm reading this right, the opponent continued to have a "pleasant" conversation while knowing that he was only doing it to "keep the opponent busy".
What a jerk.
p.s. If it was unrated, does it change the jerkiness coefficient?

No no no. I am not saying, or I hope I did not so, that what he did was planed from the start. I left the game on my own, no one can force you to do that. He did added me as a friend after I left game, and after 5 min of casual chat (thats about how much time I had left) he just went offline. I'm just saying that if he knew what was going on, he used his opportunity and kudos to him for that. I'm not mad.
I guess he had to be in the game so I could lose. Does anyone even know what happens if both players lose connection or abandon game.

Now when I think about it, chat did ended little strange.
- Not bad game
- So how is weather in Serbia?
- Hot, around 32C.
- Here its about 108F
- Uh I need to convert that.
- Take your time.
- Uf, thats around 42C, I would die on 42C.
- OK, see ya mate. offline!

I am wining in a game, my opponent says gg, we chat a little about game, but he never resigns. I forget that he did not resign and leave game. He add me as a friend, chat a little more on meebo with me, and go offline. And I see that I lost the game. He won cuz I abandoned game.

Sounds like you won really. Doesn't matter about the rating points.
My initial reaction was to say that it was your fault, but reading the discussion it seems like he was trying to distract you. Still, you need not have been distracted.

Hey Strep, but you made the last move... So, when you stopped playing it was your opponent's time... So, if just the time was running he would lose anyway... However you lost... Surely you disconnected before his resignation and before his time went away... Please, just remember when and why you disconnected and tell us... Did your opponent made something to induce you to disconnect?
So I am playing this game in live. I beat my opponent fair and square. After last move I made he would lose his only Knight left on board, and it was over. We had gg, nice after game chat, he even add me to friends and we chat in meebo, all that 5 min after game is over. Only, game is not over. I made my move, and after chat I left the game. Only thing is, he never resigned. So I lost the game - abandoning!!
Was I fooled, or was I fool?!
