No romance option for teen sim suddenly

I logged onto the sims today and one of my teen sims in my main family is maximum friendship and romance with her boyfriend Sim yet suddenly has no option for romance with him, or any sim. The romance button simply isnt there. When i click on objects there also isnt a romance option for them either. Any help? Playing on legacy edition due to my older computer and I have no mods. The boyfriend hasnt moved into the household and i checked relationships and they're still soul mates. I'm really stuck and i've searched for answers elsewhere but nothing is coming up.
