All I can say is that you have your own way of seeing life (and relationships) and I have mine. How can he be called a stalker if he tells her he is sorry and that he loves her (which, in this story, he could not do until it was too late?) Add to that, the writer lets us sense that she loves him and was waiting for him to reach out and when he does, it is too late and he now has to live with the pain.
My dear friend, I know you must have had many experiences that made you bitter, but if you only look at everything through the prism of bitterness, how can you ever find love or happiness, since every attempt to touch your heart will be seen as something evil? If you no longer want love, then at least look for ways to heal yourself so that you find peace and a life worth living.
