What do you think or do if your Sim suddenly flirts with someone that you don't like?

I have mods to stop random flirting, it won't happen in my game.
Candy Behr and Jade Rosa were the worst. Anytime my Sims attended a social event those two dogs would target my Sims and start flirting in tandem. They both get deleted in every new save and Partihaus parties at home. A much smaller home that they can actually afford.
