I understand your perspective. Few people can do what David did--it's definitely the high road.
I think you want me to say you have to be careful not to be a doormat. Not to let your spouse walk all over you especially if they're having an affair or they won't respect you. I'm not going to do that. Every relationship is different.
What we didn't hear in David's tale, and I don't know if we could look his story up on the board and see more details, I'm sure it's very old--is a good deal of the couple's relationship prior to the infidelity. You can tell that the love and friendship was strong before they had problems and that their values were related to the friendship in the relationship.
It's very popular advice on the board to be tough as nails. It isn't the best advice most of the time. Taking a hard line with boundaries is very often part of the Blame Game--and ignores the fact that the LBS often needs to attract their partner back.
I personally believe strongly in the friendship advice.
