Giving up pleasures because of living with the addiction to gamble gradually erodes the life of the non-CG. I cannot tell you what to do but with all the safeguards you have put in place and with all the information that Nomore has shared with you, I would feel you have enough knowledge to make an informed decision about what is right for you.
Anxiety cripples us and sometimes it blinds us to what is right for us. Only you can know what you really want to do. If you decide to go please ensure you enjoy every minute and leave anxiety behind. Sadly if your wife is going to gamble she will find a way and no amount of anxiety on your part will make an iota of difference – living your life in constant expectation of a disaster is soul-destroying.
I wish you well in whatever decision you make
