I got a breaker bar and put a cheater bar over it. Put both of them up against the ground with the car in 6th gear. Turn the engine over, mine came right off. Yes its counter clockwise. Other than that I don't know what to tell you except to buy better sockets 
I take it you have a harmonic dampener puller to remove the pully once the bolt is off?
