applause for an honest answer........ these answers or justifications of "we are only friends" or "it's just an arrangement, nothing emotional or physical" is . being around someone, caring for them, talking with them on an everyday level..... you will eventually develop some sort of relationship... As far as Christians go, take off the label of Christian and then do as you please! I don't think Christ would have been shacking up even if it was only a "business" arrangement.
I agree with all the conservative answers Just trying to start an interesting conversation since the forum was getting boring.
