Severed Relationship Relevance

Boy meets Girl. Boy Dates Girl. Boy Breaks up with Girl on Good Terms. Girl Never Talks to boy again, despite numerous efforts to create a platonic relationship. Scenario sound familiar?. Psssh that situation and I are best friends. So what causes this rift in platonic efforts of former lovers? Jealousy?, Envy?, Hate? I'm curious how one step to end a relationship honestly and fairly can end months of effort invested into building the foundations of a friendship and a potential relationship that may have went the distance. I'm baffled. But because i dont understand it i write those people off, kinda like someone who does something for personal gain, and bounces when its no longer personally beneficial. Pretty Much taking your ball and going home!
