The person can pull the plug on the relationship with so and so, but doesn't, though the person longed for it. So and so has been lying and can't face the truth, so they go to the person they treated badly, who wanted a good relationship with them at first but recently just wanted to get rid of them. There's a definite ambivalence of the tortured person in the song. I've felt this way with people who've hurt me too before.
