When Is Enough Enough?

In the beginning he told me that he loved me every chance he got. It would fill my heart until I feared it would burst. Near the end of the relationship he'd tell me that he hated me and worked that he had never met me. These declarations would have "I love you" minutes after he'd tell me I needed to go, that he was done with me. I stayed much longer than I should have. Enough was enough when he made threats against my offsprings. I packed up everything that was mine. I thought that would be the end of our story, but our story had an afterword. He would contact me with words of love and devotion. Every attempt I made to thwart him was blocked by a new sternly of his to contact me. When will he learn that he killed any love I could have for him? At what point will he comprehend that enough is enough and allow me to rebuild my life?
