Just an update if anyone else is having the same problem.
I had to wrap a rubber strap wrench around the regulator (mostly for protection) and then use channel locks around the rubber to turn it. It was difficult but i managed to get it unscrewed. It seems dye does a really good job at snugging the regs down.
Also, when i unscrewed the reg, i found a busted o-ring. I replaced it and it stopped the leak..
