Yup, its an act of trust and priviledge to marry another, and to be taken into the trust of that other's parents greater even still.
When you betray your spouse's trust, you betray that of their parent's as well.
An even tougher bond to rebuild than your marriage, is that between you and the in-laws you have betrayed as well. They have a lot more objectivity.. and a lot less mercy.
I can certainly understand that being the last route to take. It is powerful leverage, but you have to be prepared to play it only if you really have to.
I just thought as a parent, I don't know if I could give nearly as objective advice as I can otherwise. If my daughter came into my home and told me her husband is cheating on her I would be hard pressed not to tell her to toss him out immeidiately and not turn back... knowing full well the pain she's in. Its a much harder call when its your own kids.
