This changes the romantic status to boyfriend/girlfriend. After this, have your sims interact with one another romantically until the option 'propose going steady' appears. Information, Guides and Announcements for the EA appįrom my experience, in order to make them fall in love and have a romantic relationship with one another, you choose the romantic interaction category and have one sim 'confess feelings' for the other sim, changing their relationship status to romantic interest.
