If you're referring to Finn and Rey, the romantic feeling was there; in TFA, Finn expressed that not long after their escape in the Falcon (te "boyfriend" question), plainly laying it out there that their care for each other was not purely "lost child"/"buddy-buddy", Moreover, and in the final moments of TLJ, the look on Rey's face as she watched Finn tending to Rose said it all: after her pure jot of reuniting with Finn, the Rose moment left her feeling as if her chance had slipped away. She was not going to behave that way from the thought of Finn simply making a new friend. There was minor producer obligation to build on what was established in TFA, but the general treatment of Finn (covered pages ago) and the gross blowback from parts of the fan community to even the suggestion of a Finn-Rey romance had Rose dropped in with her out-of-nowhere "love" line. Further, every SW trilogy follows a formula with a building romance between main characters; we know who played that part in the OT & PT, and its clear which ST characters were placed in that category. Two films in, and there's no indication Finn or Rey felt anything for anyone else on that level, despite some fans trying to wish that last-second Poe introduction into a storybook romance for the ages.
