So I just started playing and had my sim on their date ask another sim to be her boyfriend, theyre together but her boyfriend keeps having a want to ask her to become his girlfriend

I'm SO annoyed. This keeps happening to me. I've tried repairing the game, I've started a whole new household, etc. I've never used mods. I can't find answers anywhere.

The last two times have been a child Sim, with the Social Butterfly aspiration... I wonder if that's a common thread? It shows their friends with someone in the relationship panel and bar, but when I hover over the want, it says it is because they are acquaintances. 

I just saved a game where this has just occurred, if someone wants to investigate it.

I notice that this want starts appearing when sims become acquaintances, then it fails to be disabled when they become friends.
