I need a way my sims do not flirt at all autonomosly, unflirty trait no works

@LadyAofPineapple Hi, thank you for your help. Yes at the beginning they need to flirt and it's fine so you can marry them. Because even if I can fill all the romance lines, they need to ask to be boyfriends, then engage, and then marry (unless I created them at the same time, together you can do it in CAS). If you follow the steps, they fall deeply in love. I changed and deleted that feeling, but they were continuously flirting with each other, repeating the same things, and that bothered me a lot. I tried to be mean, fight, etc and one of them still flirted with her (what???) For me is annoying, I finish deleting one of them or divorce them and in this way, I break the family. I would like to decide when they flirt, but no. It bothers me when they become obsessive about repeating the same action without stopping, like drinking coffee for example. But the flirting especially bothers me a lot. I don't know if I have ecolife, I have almost all the extensions except 3, vampires, magic, and another one that I don't remember. If ecolife is the one who comes with goats and small animals. yes I have it. I didn't understand what's NAP, sorry.

When you create and marry a couple in CAS, the game gives them a good amount of rose (romantic) line and a smaller line in green (friendship). I don't know why.
I tried to use traits that help don't put them in a flirty mood, like high self-esteem, unflirty traits, and so on but didn't work well. The other day I created a woman unflirty, not interested in romance or woohoo with men and women, and she went out to talk to a paparazzi, and she said something that the pink line appeared more than the middle, it was too much to me! Delete the relationship it's almost the same as divorcing them. The difference is they need to meet each other again.
It's not the woo hoo, they exceptionally do it by themselves. I wish a mod to make them unflirty without conflicts or a game option.
