It amazes me

how a friendship can turn into something more, but what amazes me more is how people can go from friends, to lovers, to enemies.Someone explain to me how something so beautiful can turn into something unbearable. Yes i know that in certain situations that involve cheating, lying, and so on why it might take time to heal. But what about the relationships that just never happened, for the relationships that never really started, and never really ended. Why is it so difficult for one to accept that the other has moved on? I think its because they still like the other person and/or it hurts to much to know they arent wanted anymore. Sometimes we just need to learn to forgive and forget, to let go when there’s nothing left to hold onto, and to give up when the battle is no longer worth it. For what is a battle that consists of only one person fighting?
