Well, I hate to say it but your wife is doing the right thing. She set a boundary (stop seeing the OW) and you crossed it. You have to accept the consequences.
I think you need to be very open with your W that you understand she will have a very hard time trusting you and that right now you don't even expect any trust, just the chance for forgiveness if you work hard enough to deserve it.
Taking additional steps to give her access to your email accounts, passwords, tracking software on the computer, GPS tracking on your phone, etc are very strong indications that you are ready to come clean for good and that you don't want any more secrets from her.
