Your story reminds me of me to a “T”…. I would suggest you get in front of this with your new wife. I too am “newly” married. For the first year my wife was aware I gambled, but never to the extent… Then the debts were not able to be hidden anymore, and the truth came out… I almost lost my best friend and soulmate because I was lying to her for the first year of our marriage.
We sought counseling, which was incredibly important, because it was the only way she could see my issue through a non judgemental eye. The counseling worked once I allowed it to. I have been 4 months gamble free. She understands, as much as she can, and I am working on getting better every day…
It just takes the effort, and the thoughts of not gambling one day at a time.
