I made a new character with the intention of romancing Lana and keeping that romance when my old romance came back. Played through the Knights of the Fallen Empire. In chapter IX, got the romance/flirt "I need to talk to one of you" and chose her and flirted. After that I had the "started romance" tag under interactions for her. That was there until I finished Nathema Conspiracy. Not only did I not get the option to propose, but that tag disappeared. I did not flirt or try to romance any other character. At all. It just appears that the game forgot the romance or the tags. From what I've seen on other treads, I'm probably totally hosed on this? Really sucks.
