Now I realize a majority of believers who see couples living together that are not married calls it shacking up. Where did shacking up come from and where in the bible does it say when a man and a woman live together its consider a sin? Now if they are fornicating thats another story but what difference does it make if they live together or not. They are going to have sex regardless where they live. If couples live together do you think it will hinder God blessings and/or leave a leeway for Satan to come in and destroy their relationship?
