Pikachu effectively represents Ash's call to adventure. To gain a girl as replacement he'd basically have to settle down, because they'd become his dueteragonist, and pikachu the side character. And that's never gonna happen.
No girl: not Lillie, not Serena, not Misty, not Lyra, not Annabel, not Macey, not Angie, not Giselle, not Bayleef, not that bloody Latias; NONE of them will win because they are at best paramours or concubines, to his true first and last, Adventure. 'His heart, his love, and his lady is the sea.'
Best case scenario they run into each other again once older and have a one-night stand, maybe a short-lived fling if they end up travelling together for a while, a temporary open relationship threesome between her, him, and Adventure.
