The Rise of Skywalker - Reylo expanded ending, still sad :-( but better

SPOILERS! SPOILERS! SPOILERS!
When I saw TROS Ben's sacrifice seemed quite throw away, particularly as Rey didn't seem that upset. Adam Driver and Daisy Ridley did an amazing job of the Kylo/Ben part and Rey's character. Initially I wanted Ben to live, and to have the happy ever after, because it just seemed so sad. But the more I thought about it the more I couldn't see where they would go. There would be hundreds of people intent on killing the former Kylo Ren (however light he has become) and I could see them being hunted all over the Galaxy. That didn't seem right either as they deserved something more peaceful. Unfortunately I think that with Ben disappearing we are stuck with the ending :-( . So. I wanted an ending that was more emotionally satisfying but that still encompassed the enormous sacrifice that Ben makes as part of his redemption, and hopefully explains Rey's reactions a little more. So this is what I came up with. I have concentrated on the end of the reylo arc rather than the mechanics of the battle of Exegol as that was the bit that bugged me. I am pretty new to fanfiction and have never written one before, so constructive comments are welcome! As Maz might say I am no writer!
