Romantic Relationships decay/become negative fast with no interaction

I'm having this issue too.

Yeah, my sims are married with 4 kids (and one on the way), but their romance bar keeps draining. It just happened all of a sudden. In the relationship panel it also says they're "just good friends" and they don't have wedding rings on. 

I've been pretty fortunate to not experience any real bugs since the first Lovestruck update, however, over the weekend (after Lovestruck was released) I started experiencing this. It started as a slow decline in romance and at first I thought it was a part of the new attraction system, having to constantly maintain and work on my sims relationships. I thought that made sense at first. Yesterday though, I could see with my own eyes, how the romance meter went from being full to be completely drained within a couple of seconds. My sims are all of a sudden Very Unhappy in their relationship and one of them even threatened with divorce. Hoping EA will find a fix for this soon and push out yet another bug fix patch...

im having this problem allso i tired going on a date but in like 5 hours after the date the bar dropped to red while they where at work.

I am also having this issue. I don't know if it's a bug or a new feature of romance dynamics but I don't like it lol

Also having this same issue. I’ve spent more time actively working on sims relationships with the love struck pack than I ever have before but the inconsistent romance level/satisfaction is beyond frustrating. 

I have this problem too, it's horrible to play with this bug

Also having this issue now. Essentially having to ignore the new lovestruck / relationship features for now since I can't use them to make relationship progress. 

got same bug too, i try to remove mods but idk ifthis gonna work

after installing a new add-on, the romance bar drops in a few seconds even though there is no interaction between sims idk what i am supposted to do bc it prevents me from playing the sims
