I sometimes have other household members follow the sim I'm travelling with to other lots. I don't know why. If I wanted them to come I would have brought them.
But I think you're missing the point of that aspiration. It's supposed to be difficult. Then you complete it and no one will be jealous anymore. Just go with the drama for now. Maybe Paolo will break up with him and that is what makes him realize that Paulo is the one. Then when he finishes the aspiration, he can do the soul mate one and win Paulo back.
