Aristotle, (384-322) said, "Nature abhors a vacuum."
Apply that philosophy to relationships, be careful when you successfully free yourself from a toxic and abusive partner that you don't adopt Aristotle's philosophy otherwise you may find you are back from where you escaped.
"The reasons people stay in an obviously unhealthy relationship are as varied as the relationships themselves. They may stay for financial security, to give children a two-parent household, because they love their spouse or partner, or for reasons they may not even be able to articulate."
