Auto Flirting should be a player choice

We seen it happen loads of times. 

You have your 2 Sims out on a date, an outing, or you have sims over to hang out! The friend and romance bar is full or going well and all then suddenly...ANGER. What happened?? I just followed one of my Sims to have them do x,y,z ! 

Turns out, the Sim SO decided to suddenly flirt with another flirty or interested sim! You looked away for 3 seconds and now the relationship is ruined with trust issues and hurt feelings! Even if you have crafted that Sim yourself to be Good and Loyal, it doesn't stop them all the time...and somehow they automatically cheated by flirting back, even though it was completely out of your hands! 

So this is what I suggest. 

A base game update that when playing a household (OR you have Sims out in a Group, say for a date for example), any NPC Sim that begins to flirt or romance one of your Sims triggers a pop-up to either "accept" or "reject" the flirtation, instead of it just sort of "auto happening" and causing a cascade of negative moodlets. This way you are not caught off-guard and can choose if you want the drama or not.

Maybe even one of the two gain a positive/negative moodlet as a result. Maybe a confidence moodlet or romance bar boost if their SO rejects the flirtation, or an angry/sad moodlet for betrayal as they should have chosen to be faithful. 

It would be nicer to control this aspect, just as we can control certain jealousy aspects. Or perhaps have a toggle on/off button specifically for flirting in conjunction with the ability to choose to accept or reject.
