Same here. In my case, my romance with Wyll didn't progress at all after the dance and kiss scene. All I could do for the rest of the game was chat to him about 'us', and get a little kiss. The proposal scene didn't even trigger for me. I filed a bug report as I'm wondering if a whole heap of romance stuff just didn't trigger (like what people complained about with Minthara when the game first entered full release) but if not, I hope the writers will expand on this significantly in the upcoming patches. Hopefully they're reading along here. I just finished the game after 96 hours, it was amazing, but the Wyll romance was a let down.
