Quick question for those further along in the game than me.

Is the beginning of the romance with Shadowheart conditional on solving the main quest with the goblin camp?

I ask because I already managed to increase her approval to the maximum and she told me that she absolutely trusts me, but still she did not offer me anything resembling the beginning of a serious relationship.
Practically all the other companions have already offered me something similar before the goblin camp, so I'd like to know if I did something wrong or if I just have to wait a little longer.
