How to be Honest, without losing built up trust?

[Marc Stuart]

Thanks for the comments. I know I need to resume my therapy with GA, so will be going back for my weekly session. I am no worse off financially, so I don't feel strong enough in coming clean with the wife. She has been through enough over the years, with my addiction, for me to drop this bombshell. All I will be doing is clearing my concience, and for the sake of the arguments (She will never understand the mind of a compulsive gambler), I am thinking I can sort this blip out myself.
Perhaps this is the easy and selfish route to take, but I can't see what benefits coming clean will do? I know being honest is important in a relationship, but I can see this bringing more harm than good?
