It's very likely MCCC. You'll need to configure it properly for however you want to play. You can get to the settings by clicking on a sim's computer and selecting "MC Command Center" and "MCCC Settings".
The good and bad...
The bad is there are a LOT of settings. It's very easy to get lost with them all. So, the best thing to do is go through them, just look and get familiar with them. If you're not sure what a setting does, it's best to leave it alone. You can easily change things that may have unforeseen consequences.
The good is, once you configure things, you'll NEVER have to do it again. The settings are saved externally and will apply even if you start a whole new world/save game.
The settings YOU might be looking for are these...
MCCC Settings\Relationship Settings\Breakup Settings
MC Pregnancy\Pregnant Sim Selection
MC Pregnancy\Partner Sim Selection
If you want to disable random breakups: Go into "MCCC Settings\Relationship Settings\Breakup Settings" and make sure "Couple Relationship Change Percent" and "Spouse Relationship Change Percent" are both 0.
To disable random pregnancies: Go into "MC Pregnancy\Pregnant Sim Selection\Pregnancy Percentage" and set all four age groups to "0"
To disable random marriages: Go into "MC Pregnancy\Marriage Sim Selection\Marriage Percentage and set all four age groups to "0"
There are a lot of settings... You can have it bypass only played households, bypass sims that have active romances with a played household, etc. There's a TON of options. If you have any questions, feel free to ask.

Thank you I was having the same problem with the MCC mod it was confusing know I can re add it again.
It can be quite daunting with all the settings, but it's best to just get familiar with them. If you feel adventurous, maybe make a change, remember what you changed, and see if it has the desired effect. If it doesn't, change it back. It'll always tell you what the default was.
Don't worry a whole lot about the settings. If you have a question, just jump in here and ask. There are some of us like me who've been using it since it was first released. We're extremely familiar with it. I've been using mods like that since Nraas back in Sims 3.
If worse comes to worst and the settings get all borked, you can reset the whole thing easily enough. Just exit the game and delete the MCCC file "mc_settings.cfg". Re-run the game and it'll create a whole new one back to the defaults.
AFAIK, there is only one setting that "might" screw something up. If you have the mod, "Simulation Lag Fix", I've heard that changing the game time speed in MCCC from the default of 25 might mess things up. I've heard changing MCCC's game speed can interfere with SLF. Not sure how though. I don't use it as I'd rather have longer days. Mine's set to 30.

Hello I have a question you know when your game updates do you delete your save or do you just delete your mods and cc then add it back when your game has updated.
do these changes work for my own households or other households or even both?
