Reactions from Romantic Interest

[Bugdozer]

I have a Sim who I want to marry with the maid who cleans his house. However, he already has another romantic interest - and she's pregnant with his baby. She lives in another house entirely.
I have never proposed going steady with the pregnant Sim. But what I want to know is, how negatively will she (the pregnant Sim) be affected if the father of her unborn baby strikes up a romantic relationship with his maid? Will she become enemies with him? I want to avoid unpleasantness if at all possible. I know how this would affect someone who was Going Steady or Married etc but I'm not sure how seriously they take it just as Romantic Interests.

Hi Bugdozer! It looks like nobody answered your post. What will happen is that after you pursue romantic actions w/the maid enough times, you will get the opportunity to "break up with...." the other lady. She will become enemies w/the maid and I *think* also her former boyfriend. It will gradually decrease though. You can also use the master controller mod to erase it altogether if you want. I'm not sure if this will come up if they're not girlfriend/boyfriend though. You'll just have to experiment. I'm thinking that if he's unattached (not going steady or anything), you should get the opportunity to marry the maid eventually.

The game treats romantic interests as seriously as it does marriage or going steady, especially if you have Generations and the romantic reputation system where any romantic interest can accuse you of cheating.

If you don't want your sim to continue the romance with the pregnant sim, you can go under mean interactions and "ask to be friends" and it will remove the sim as a romantic interest. The amount of green in the bar will take a hit, but at least that can be easily rebuilt with friendly interactions, and once they aren't romantic, no jealousy will be expressed. Even with the broken heart moodlet she may get, there won't be jealousy, just her periodically crying about their romance being over.

Be warned that if you do have the romantic reputations in the game, if your sim marries the maid but that other sim is still a romantic interest in the panel, there is always a chance your sim could be autonomously accused of cheating out of nowhere, and without cheats, that is a huge pain to fix without it ending in an autonomous divorce you can't cancel.
