If you dont like the way some sims look,and dont like your partner,make your own!Just go to create a townie, and that sim will immeadiately go to your house.Just talk and talk, and be sure to make one of your townie's skills flirty or it will be harder and longer to make a great partner.And you also can invite that sim over anytime so just keep working hard and i hope this is easier for you.This is for sims 3 for 3ds.
