SPOILERS
Hmm... if I remember correctly Bastilla is pretty sensitive to what you actually say to her. In my game I actually very much tried
not to tease her or provoke her at all (I was on lightside though). If I remember correctly the "kiss scene" (the key point in the romance plot) occurred on Ebon Hawk right before being intercepted by the Leviathan (which in turn occurs in transit between planets before finding the last Star Map).
If were you I would just continue with the game, get back to Ebon Hawk and see if you get to talk with her more.
You may want to play with
KOTOR Savegame Editor (KSE) and set some variables (global and for Bastilla) there to get on with the romance plot (you are going to have to figure out yourself which variables are responsible for the plot).

this forum out which may assist you more.
Sorry, I can't help you more.
