Good luck Sammy
While you are really suffering at the moment it’s great that you have commited it to writing in an open forum and taken positive steps to stop.
You really ought to consider telling your family as their support will be far more effective than all of the other measures put together. Would you trust your wife to handle all of the family money for say six months. If you have no money to gamble then the ability (and temptations) would be disallowed. She will probably go ballistic at first but after the annoyance/anger/disappointment/ recriminations it’ll all settle down quite quickly and you’ll be in a better place with someone to share your route to recovery.
I wish you well.
