Stormpilot and Reylo, everything to date has been platonic. That could change once The Rise of Skywalker rolls around this December, but clearly this isn't an issue on the forefront of Lucasfilm's mind.
To be fair, the sequels have toyed with the concept. Upon meeting Rey in The Force Awakens, Finn is quick to ask his new companion if she has a "cute boyfriend" back on Jakku. At the very least, that suggested Finn was initially attracted to Rey, but the film didn't really flesh things out beyond that. And in The Last Jedi, Finn (separated from Rey for a majority of the film) went on an adventure with Rose, culminating in the two sharing a kiss on the Crait battlefield. It looked like there were seeds there to further explore in Skywalker, but Lucasfilm has gone ahead and nixed that already.
In the new canon novel Resistance Reborn by Rebecca Roanhorse (which is now available), there's a scene where Poe asks Finn if there's anything going on between him and Rey or Rose:
Poe hesitated before he asked, "So the two of you aren't..."
Finn looked puzzled at first, but then his expression shifted to amusement. "No, nothing like that. Just friends."
"And Rose?"
"Oh." Finn shook his head no. "We talked about it, and Crait was... a moment. But that's it. Friends there, too."
It's probably smart for Star Wars to go this route. As indicated above, the new films haven't done much to set up a romance, which differs from the other two trilogies. The foundations for an all-out war with the First Order. Once the galaxy is saved from evil (again), then maybe the heroes can look to settle down with a significant other.
It'll be interesting to see if The Rise of Skywalker addresses this development. Obviously, not everyone who sees the movie will have read Resistance Reborn beforehand, and The Last Jedi did end with the tease Finn and Rose's dynamic was a little more than just friends. Normally, the Star Wars canon novels are nice supplemental materials to the films and aren't required to understand the movies, but this case is directly related to a sequel trilogy subplot. It would be odd if The Rise of Skywalker just dropped Finn and Rose's potential romance without making any mention, so it'd probably be a good thing to touch on the state of galactic love affairs in a line or two of dialogue.
