It was good to hear your news and that you have been brave enough to tell your wife and others. It will be a weight off your mind and will allow you to be honest from now on. Being deceitful only adds to the shame we feel and gives us another excuse to place a bet.
I hope you can build on this by allowing your wife or someone close that you trust, to handle your finances until you feel stronger. You may want to point your wife to the friends and families part of this forum where she can read posts from others who are living with problem gamblers and can find strategies to help both herself and indirectly your recovery.
Keep posting – I will be looking out for more from you.
