I know the feeling of relief Arcola, because I did the same thing with one of my Intel sources. But, I'm going to have to agree with Starsky. Your W has done you the disservice of deceiving you and others, so Intel is crucial for verifying the truth going forward.
When I fessed up to snooping, my W actually also fessed up that she was snooping on me too. I was already aware of this since she was not being very clever. I didn't show her all my "cards" and I still am able to keep tabs on her although she moved out several weeks ago.
Unfortunately, I think the only gain you'll have from her knowing about your snooping is detachment like twinmom related to. She probably will become better at hiding things from you now, but isn't likely to change her ways just because you are in the know.
Because I've maintained other sources, I know that my W is still stalking OM and his GF daily, don't believe she has contacted him, but do have proof that she is trying to get a job working with him now and is taking every opportunity possible to cross paths with him. I also know she has kept his phone number. I was able to figure out a way to mess with her and change his # in her phone contact list remotely. She corrected the error once, but I did it again and she hasn't caught on, so that is why I don't think she is in contact with him...
