How can I rewrite this segment of a fairytale to include a flashback and flash forward?

Original part:
At first Rapunzel was terribly frightened when a man, such as her eyes had never yet beheld, came to her; but the king's son began to talk to her quite like a friend, and told her that his heart had been so stirred that it had let him have no rest, and he had been forced to see her. Then Rapunzel lost her fear, and when he asked her if she would take him for her husband, and she saw that he was young and handsome, she thought: 'He will love me more than old Dame Gothel does'; and she said yes, and laid her hand in his. She said: 'I will willingly go away with you, but I do not know how to get down. Bring with you a skein of silk every time that you come, and I will weave a ladder with it, and when that is ready I will descend, and you will take me on your horse.' They agreed that until that time he should come to her every evening, for the old woman came by day.

Method's I decided on: flash back/forward.
