I just am beyond the stage of frothing rage and into blinding apathy with her.

The same here. I'm slowly but surely reaching the stage of "whatEVER!" I tried to like her, I tried to reason, I tried to rage. My opinion isn't important anyway so why bother. Bela is a permanent fixture and no amount of raging will get her off the show since even Kripke himself is in love with her. So yeah *shrugs*
