Picked up Neera, killed the goblins, butchered the Red Wizards, saved Adoy, and promptly started romancing her at the first opportunity. I didn't count, but I think we had at least two meaningful dialogues after that, and the last one we definitely kissed or something. However, when I told her to speak of our sentiments further, she said we should wait for the right time. My dwarf is kind of impatient. It's been two weeks in-game at the very least.
Maybe I need to advance further into the next chapters? I'm not yet in Chapter 5, thus no access to Baldur's Gate itself. I know she has a minor quest in the city - some gold she owes - so maybe that quest must be completed for the romance to resume?
*Edit* Also, the wiki doesn't say much in regards to all three romance quests in BG1EE. I'd volunteer to write it, but I don't know much.
