MattDad, this is my take on all of this and the possible reconciliation.
1. No contact with OM at all. Every cell phone can have numbers rejected same with texts, set it up on her phone. Put an app on that shows what she is up to as well, call/text/web monitoring. If she balks, threaten to walk. She needs to gain your trust, you don't need to gain hers.
2. STD tests all the way around.
3. Crisis counseling would probably be a good step as well.
4. GPS monitoring in her vehicle. You can buy a device for under 50 bucks that will give you all the data you need. You can do it off of her phone as well. Remember, she has to prove herself to you, not the other way around.
5. The OM, call him and tell him he is finished with her. Tell him that your wife gave you all of his info and you will be more than happy to forward it to his wife, family, friends co-workers, etc. Make her write him a letter or email telling him the affair is over.
6. Passwords. Demand all of her passwords for everything.
And remember, if she balks you walk. Simple as that. Because in the end, wouldn't it be nice to know that you can't trust her now when she is on her best behavior as opposed to going through this again in a few years?
