Help save my sims marriage pleaseee

I play Sims 4 on PS5, base game, get to work, get together, get famous, vampires, realm of magic, jungle something lol, and we had city living but its not working at the moment. 

I have two legacy sims, ive played with then exclusively since 2020 maybe even sooner. I built them for each other specifically. 

now when my husband sim had to start mischief interactions (to complete an aspirations) he started to randomly be mean to my wife sim. I just couldn't leave them alone or he would start acting up and push her buttons. 

My sims have been soulmate bonded and had thier relationship at 100 percent (both friendship and relationship/love) since I made them. we had one daughter then triplets. a man was flirting with my female sim at work and it made my husband sim jealous and he started insulting her or yelling at her constantly. I used others tips and tricks, we talked about our fears, we apologized constantly we have no negative sentiments whatsoever ever but when I try to get them to get along better they end up fighting. 

I have discussed fears many different times. 

I have zero negative sentiments towards each other.

I have moved out my husband sim and moved him back in

I do not want to divorce but I cant leave then alone or he insults her to the point of almost being in the red. 

Any advice is welcome!
