Glad that you enjoyed the film, I also think rather highly of it. In my humble opinion I didn't see any signs of the connection between Rey and Kylo being one of romantic interest. In my mind I saw that Rey strongly believes that there is good in Kylo and feels that she can help him find redemption, her desire to do this isn't driven by any romantic notions but by her belief that she has a calling from her connection to the force to pull another force user towards the light. I do however agree that Adam Driver's portrayal of a character at conflict between both sides of the force pulling at him, was very strong and believable.
