About a year ago I learnt the hard way it is best to monitor anything to do with money or paying bills. I have always paid the main household bills and my husband just paid bills like his cell phone, car tax etc. I had no idea he was having any problems until he started complaining that his mobile phone provider had changed his phone number without his permission. It turned out that instead of renewing his annual plan online, he had signed up for a whole new subscription complete with new phone number. He insisted that this was not what he had done and complained that it was their website that was not working properly. It was a major tangle to sort out as apparently it could not be canceled. I now observe exactly what he is doing anytime he is paying any bills, and have made sure I can monitor all his individual accounts, including recently suggesting to him that I become a co-signer on his individual investment accounts which we have now done. I hope we have this aspect squared away, but I do wonder what is going to come out of left field next!
