We're not sure if we'll see Rey and Kylo Ren unite in Star Wars: The Rise of Skywalker, but this post argues in favor of the Reylo pairing.
“Each trilogy has had its central love story—Anakin and Padme, Han and Leia—and both so far have ended in tragedy. Those opposed to Rey and Kylo’s union might tell you Star Wars isn’t about romantic love. I would argue the opposite: That it’s all about love, in its many iterations. Romantic love is part of that, and it doesn’t make characters like Rey lesser if she’s drawn to a soulmate, or if she looks for love in the arms of a man. Redemption arcs in fantasy are almost never rooted in a woman’s desires. But female desire isn’t a weakness. In this case, it could be the most powerful thing in the universe.”
