I noticed that things like compliment appearance seem to work, but anything else doesn't.
Compliment Appearance is your best friend in these situations. Just start slow and low, throwing it in every 4th or 5th interaction. Pepper their conversation with flattery and jokes. It might help if they're doing something together, like playing chess or Don't Wake the Llama, or dancing.
It might take a few conversations, but it'll nudge the Romance bar up a little bit every time.
I've had really good luck with the "Bold Pick Up Line" interaction when my Sim gets Confident. It seems to have just the right amount of humor to keep the other Sim from rejecting it.
Best of luck! You'll have them back together in a short time, I'm sure. And when you do, post some romantic pictures!
