It’s emotional and mental blackmail. Her saying that she will kill herself if you do not help her is completely out of line and it is showing you her true colors. She is guilting you into helping her and into having a relationship with her. Would you honestly want to be in a relationship with someone who uses guilt and manipulation to control you?
A path without peaks, valleys, winding roads, or without starts and stops that require you to pivot isn’t a life worth living. Indirect and crooked paths that require us to deviate from our projected paths solidify our mental fortitude and increase our stamina, self-confidence, and self-love.
