Aslan tell Susan and Peter that they are too old to return, and that they have learned everything they can "from this world". It is time for them to move on, to find who Aslan is in their own world.
Susan and Peter can't return to Narnia because they have grown too old to enter that world as the magical portal only allows children to pass through. The rules of Narnia dictate that once they have reached a certain age, they are no longer able to access Narnia through the wardrobe.
Peter and susan aren't the last ones to leave Narnia! What happens is that aslan tells peter and susan (in the episode prince Caspian) that tis will be their last trip to Narnia this is because they are getting to old Lucy and Edmund do have a couple more trips there.
It's explained in "The Last Battle" that Susan became too obsessed with material things and the things of the world. She allowed these thoughts to overwhelm what she learnt as a child and Queen of Narnia.
By the end of Prince Caspian, Susan and Peter are too old to return to Narnia. They are told that they have learnt all they can from the world of Narnia, and that they must now seek Aslan's identity in their own world.
Later, in The Last Battle, it is revealed that Susan has truned aside from what she learnt in Narnia, and embraced the materialism of her world, discounting their adventures in Narnia as "fairytales". She represents the Christian who is easily lured from their faith by worldly things.
Peter could only go to Narnia as a child. After "Prince Caspian", he was too old, having learnt everything he could learn from Narnia. The same situation applied to Susan.
Peter returns in the final book of the series, The Last Battle. Susan never returns, because she has stopped believing in Narnia.
Peter was taking an important test at the professor's small house, and Susan was in America.
because they have become to old for narnia, but peter does go back in the last battle,sadly susan never goes back
