How can you get even with a fulltime manipulator?

Stay away from him, learn to avoid his type altogether and remember what they always say... "Living well is the best revenge." All cliches aside... don't stoop to their level and give them the benefit of seeing you making yourself low to get revenge. It will kill an enemy to see you walking by acting as if you could not possibly care less. It can be hard to resist the temptation to get even, but when we move on and do our best to find happiness and don't stoop to their level, we are far better for it.
