Serious Need for Romantic Interactions Update

Ugh is it me or is the Jungle Adventure making Sims behave even more disloyal than anywhere else? My one Sim was working on a relic and some random woman happened to walk by and he started talking all flirty sounding to her. Her icon in the action bar had a heart on it, but I couldn't click on it in time to see what it was all about. My Sim was NOT flirty at the time, he was very focused and he's very married. I'm sooooooooooo tired of that nonsense already. I don't understand how it can't be implemented in the game to have that loyalty trait. I know there's people out there that don't mind the flirting and fooling around and apparently that's given to them. Why not give us that want the loyalty thing what we want???? I don't even know why I bothered with the soul mate thing when all it does is let me hear the spouse's complaints and get soothed. What a dumb reward for that aspiration. LOYALTY should have been the reward. Pffft....but what do I know.
