Most likely, you just need to wait a while to get the next romance dialogue. If you want to make sure the romance is indeed active, the console command was mistyped in the "SPOILERS GALORE" post about the Jaheira romance. It's actually:
CLUAConsole:SetGlobal("JaheiraRomance","GLOBAL",1)
You can replace JaheiraRomance with any of the other applicable NPCs, such as AerieRomance, ViconiaRomance, or AnomenRomance. Just remember that it's "GLOBAL," not "GLOBALS." Give her a few seconds to respond. If she still doesn't, you may need to rest first.
On a side note, the romances are generally more rewarding if you let them play out by themselves, instead of going through them quickly... at least the first time. Hope this helps, and good luck with Aerie!
