Gooch, i disagree. I told my wife that I had no intention of being her friend -- let alone "BEST friends" -- if she chose to end our marriage this way (by having an affair, lying to me about it, and cutting and running and not even trying to work on the marriage).
It had a huge effect on her, and along with exposure to her parents and our daughters, was probably the single biggest reason she reported wanting to reconcile.
I can assure you, there was NOTHING in any way "needy" about the tone or content of my "I have no intention of being your friend" talk.
