I made my sims wife flirt with her father-in-law (my sims dad) and all romantic interactions were there, but after that one flirt was done, all romantic interactions disappeared except for give flowers, and the irresistible actions for the father-in-law, help?

Nevermind, it's back, i don't know why but it's back? i did nothing btw, i just continued playing? lol

Was he doing something else? I've noticed the available actions change if a sim is sitting down, or watching TV, or exercising, etc.
