I wouldn't have done it for the "so I can't check the phone/text logs" reason (I would have instead told myself to suck it up, or I would have asked a trusted 3rd party to keep an eye on the intel for me and notify me only if there was some immediate threat to me, my family or my finances) . . . but I definitely would have cut it off. I would have -- and DID -- do it for the "I have decided that I'm no longer willing to pay for anything you use to conduct your affair, or to run away from our marriage" reason.
