Hi there!
I've scrubbed the forums for my q and I couldn't seem to find what I'm looking for so hopefully you guys have an answer! I'm currently doing the Bachelor challenge and my Bachelor sims has started romancing multiple sims. Each time he romances anyone other than someone he has a 'Romantic Interest' their relationship decreases. I flicked through the options in SP and MC in my game and didn't really find what I was looking for, same with the Nraas forums. All I have seen is how to disable jealousy through Woohooer but I'm not particularly sure that's the same thing. Any help would be amazing!

TL;DR:
How can I disable relationship decay or jealousy when it comes to romantic interactions?

Sarah_Sims notes on her page to use Nraas Retuner
City Hall > NRaas > Retuner > Settings > General > By Tunable XML > Sims3.Gameplay.Socializing > SocialComponentextend the hours higher kMinHoursToHoldRelationshipState = 99999 (Default:48)

For jealousy you indeed need Whohooer

In SP you can look for romance and flirt options

Thanks for the reply!

Can you explain to me exactly what those Retuner settings will change? Thanks!

f.i.
kMinHoursToHoldRelationshipState
means the minimum hours to hold the relationship state,
default is 48 hours, means after 2 days it decays
if you increase the hours it stays longer
99999 is then about round 4167 sim days, which is like never, depending on your life span.

Ah brilliant! Thanks!

And after reading through the SP and Woohooer links you provided I'll be downloading Woohooer to achieve what I'm looking for! I thought the jealousy in that mod only applied to woohoo and not romantic interactions! Thanks for the help
