Cheating Sims!

I had a sim couple living in the Nookstone lot in Oasis Springs. The female was super pregnant and taking a nap in the little bedroom nook. Meanwhile, her fiancé was getting it on with her sister in the shower. After they did the deed, they shared one last kiss in the living room nook as she was waking from her nap. Even though they were on the other side of a wall where she could not see them at all, she immediately knew they were cheating (because game code recognized her as being in the “same room” as them since open concept) as soon as she woke up and she got super sad and angry and it totally wrecked the storyline I was working on. UGH. Had to use some cheat codes to repair their relationship that night haha. I dislike when the stories I create in my head don’t play out organically on screen and I have to fudge things like that.

Not exactly the same, but one of my SIMs is a serial romantic who likes "no strings" fun. I love him but he's the SIM equivalent of Teflon ?
Unfortunately, he had a fling with Dina Caliente who, it turns out, is extremely clingy...
She texted him asking to hang out when he was in the middle of a tryst with Candy Behr and called him twice when he didn't answer!

I don't use to have this kind of drama cause the reactions of the cheated sim and the cheater are too mild. Yesterday i went in a mod shopping mood and i've added some mods. One of them is realistic reactions and in my playtest sims got really angry, and kids really sad for seeing their parents fighting about it. It seems that im going to have more of this kind of drama from now on ?

OMG....LMFAO!!! Where do I start? If you can think it, it's been done in my game. But my fav moments are when Shinya and Bella were a thing. They had 3 kids together. After the twins were born she asked him to leave Mortimer and to marry him. Bella refused and broke it off with him refusing him to be a part of his children's lives. Heartbroken and devastated he got in a rebound relationship with Zoe. When she wound up pregnant, he bought a house and asked her to marry him. When the bay was born it was discovered that J Huntington was the father, not Shinya. He broke off the engagement and moved out.
