Hello to you and welcome to the forums, you're found a great place to start looking into what it is that will help you on your journey.
Maybe in time, when you're making steps to recovery and if you want to you'll be able to tell your wife what happened and she won't take it so hard because you're gaining her trust that you are seeking recovery.
Don't worry - there's always a way forward to healing, both yourself and your relationships. Well that's been my experience anyway. :-)
