If it makes you feel better, I didn't get that impression. My perspective from the Force Awakens is that Finn fell for Rey, but Rey saw him as more of a friend. Finn still loved Rey at the beginning of the Last Jedi, but Finn fell for Rose over the course of the movie. Rey's look at Finn at Rose's side didn't seem heartbroken. It seemed somewhat neutral like she was just taking in the information that Finn cares about Rose. I think the Rey and Kylo scenes had strong romantic undertones. When Kylo asked Rey to join him, I think his main intentions were romantic. Rey clearly cares about him to some degree, but it may just be a strong conscience that led her to try to save him. On a related note that you may not like (because it may hint at a separate love triangle), Poe and Rey's introduction included a call-back to Empire Strikes Back by Poe responding "I know." I think what happens will depend on whether or not Kylo survives the trilogy. If he does, I would assume he and Rey will get together.
That doesn't make me feel better at all. Kylo and Rey together would be the worst possible thing to happen in these new movies. Why would I ever want Rey to end up with someone who tortured her, killed her friends, and has no desire to change? He was given two separate chances for redemption, and he turned them both down, first by killing his father, and second by trying to kill Rey again. It's time for him to go down like the villain he is. Putting them together just to redeem him would be a terrible choice in writing. It's a god awful pairing.
