Let go of what was never really there.  Your intuition knows what I’m referring to – the pictures in your head that go against the present reality.  Remind yourself that not everything is meant to be, and you have to accept this.  You have to seriously sit down with yourself and come to grips with the fact that you were wrong about it all along.  It was just an illusion that never really was what you thought it was.  It’s one of the most difficult realizations to accept, to realize that you feel a sense of loss, even though you never really had what you thought you had in the first place.  The key is knowing this, learning from it, letting go and taking the next step.
