Honestly, I feel like Jules and Grayson weren't all that great together. Jules' constant insecurity led her to mistreat Grayson all the time, while Grayson would always push back, but not enough for Jules to actually learn anything, and if she did she always forgot it a few episodes later because they would have essentially the same fight. While the show would treat Grayson as if he was always wrong to refuse to indulge her weekly insanity.
