This is a long story, so relax and enjoy. Also, please note, she was created through NRass StoryProgression. Which is why she's able to do a Lifetime Wish like an active Sim.
So my main Sim, who just got his lifetime wish fulfilled, thought maybe it was time to settle down and get to baby-making with a female he would like. Maybe start a legacy family.
He got a dating profile from "Benni", which is pretty funny as my Sim's name is "Benie". So, I wanted him to get to know everything about her, especially the fact he has Commitment Issues. She fell for him instantly, like it was love at first sight. She has the Flirty trait which made it easy to get up the Romance ladder.
So I thought "Hmm. Maybe this could work". I had him do love letters to her, go on a few dates, WooHoo'd with her in a haystack (twice..heh). Had a Ghost Hunter job that took me to her place. After doing his job, He did another WooHoo with her in her bed.
Nice reward, huh?
Decided we should go steady. Did another date. Then I proposed and married her on the spot. Now, here comes the fun part. "Fun" as in finding out she's a heartbreaker, but not until having a child with her.
I discovered she's WooHoo'd with several men before she met Benie, had kids with them, and it seemed I was next for her to break up with. She's 8/10 away from completing her 'Heartbreaker' Lifetime Wish.
So I ask you, should this marriage last, knowing she ... was with other men before meeting me? It just scares me she's going to break up, after I put my heart and sole into making this work, for him.
