Maybe just maybe being totally open about your addiction with your wife could help ? So you do not have to face this alone in that way. I hear you on the stresses of possible loosing homes and such like. I hope you work this through and find the solutions you need. As you say the one thing we do not need is gambling. That way lies only ruin and madness.
Maybe your wife will work things out anyway as you have shown her the forum …. keep taking it one step at a time hour by hour if need be. Each day you dont give into the urges is a victory!
