I've had the same experience. Shadowheart hinted at the possibility of romance but that I'd been too against her, which was kinda weird because I'd been playing in line with her approval throughout the game so far, but I guess it was just a matter of not having met her approval requirement. Shadowheart didn't hint at anything at all, Gale expressed interest as did Asterion and I think Wyll did but I can't quite remember. So it all felt kinda rushed and awkward, especially since I had only rested at camp about three or four times up to that point so there hadn't been a lot of interaction between us yet.
