I sincerely agree with the fact that it is her God given responsibility to forgive her husband, and to try and understand by talking with him what caused this sin to take place to begin with, and without a doubt the husband did sin!
What troubled me in listening to Mr. Robertson in this interview was his "condoning" tone concerning the sin of infidelity~~you cannot just make the blanket statement that he is a man and basically, "That men are prone to wander" and that it should be the wife's sole responsibility to make that home so happy that he won't want to! A marriage should be 100%, 100% on both parts! That would be like saying that God made women to enjoy caring for and making purchases for her home so it should be her husband's responsibility solely to keep her happy so that she doesn't need to purchase so much~~I for one was offended by his "almost apologetic" tone concerning the husband's sin~~falling back on the old adage, "Well, God made me that way" to me is unacceptable~~not trying to be disagreeable, just did not quite see this the way you did :)
