But we are not "Affair Proofing" our marriage. We are making it less likely that an affair will happen. Also, that "good fog" must clear to allow us to make the best decisions possible about whether or not to marry someone. It has been stated on here many times by much respected, knowledgeable folks.This is where I think knowing human nature and avoiding PC views is needed. We know one way to avoid falling in love with a co-worker is to not allow the interaction to become even slightly inappropriate. We know (I think) that many women who have lost respect for their husbands can't really control the innate feelings and are resentful. It reiterates that having boundaries, being respectable, and being respectful, also create a fog. A good fog so to speak where those chemicals tell your spouse they want to be with you.
I am agreeing with you in part as I have done with others in this thread. I am not disputing that we need the tools or that the tools are good or that they help to make a marriage less prone to affairs. What I am saying is this, no marriage is "affair proof", not even with the best of tools and the smartest folks.
