Been together 9 years, married 6, no kids, no property, no debt.
Based on this alone I suggest you RUN and don't look back, it takes years to recover from infidelity with a very remorseful WW doing all the necessary work and heavy lifting to restore the destroyed M, your WW is light years away from being one, she got busted so right now she just regrets getting caught, she's still lying to you, you only know the tip of the iceberg. POSOM left OBS to be with your WW, the fact that your WW moved exactly to the same city where POSOM lives and was playing house with him already suggest she was test driving POSOM and getting ready to leave you for him, make no mistake about it that was their plan.
Again I always suggest D when it comes to LTAs, and even more so if there are no children and lots of financial entanglements involved.
If you insist on trying to R, here's a few of the basics:
1) EXPOSE the A with ALL family and close friends without warning (very important), exposure typically kills the "beautiful, romantic and excting" aspects of the A and replaces them with pure shame and embarrassment, the more she hates the A, the more she will hate the AP.
2) Demand she quits her job and returns to your city on the first flight TOMORROW, upon arrival aske her for her unlocked phone and don't give her time to clean it, if she has already done so, get it anyway to run recovery software like (Dr Fone or Fonelab). You should know what you are trying to forgive.
3) Demand she sends an NC FOREVER text to POSOM, one that you approve, short and to the point (no sweet goodbyes), make sure you watch her hit "send". She also needs to tell you immediately if POSOM tries to contact her, no questions asked. Also ask her who else knew about/enabled the A, they are not friends of the M and need to go too, another consequence of her huge betrayal.
4) She needs to offer full on demand access to her phone and all electronic devices and passwords FOREVER.
5) Demand she gets tested for STDs/STIs (full panel), yes she's been playing russian roulette with your health.
6) She needs to go to IC with someone who specializes on infidelity (very important), to find out her whys. Forget MC for now, at this state it's typically a waste of time and money.
7) Have her read "Not Just Friends" by Shirley Glass and "How To Help your Spouse Heal from your Affair" by Linda McDonald, both available for download.
8) Consult an attorney to know your legal options, and while you're at it, ask about an enforceable postnup in case she cheats again, she's a proven cheater and liar and you need to protect yourself financially.
9) Demand she gives you a complete written timeline of the A, subject to a polygraph. Then tell her to read it out loud to you, it helps with remorse, no remorse no chance to R successfully. Ask questions and make sure you record it so that she doesn't try to change her story later.
If she refuses to do any of the above, file for D and have her served without warning, you can always stop it if she comes around before it's final, if D papers and full exposure don't shock her back to reality, then nothing will.
Keep posting frequently, the collective wisdom of SI could help you go through your difficult situation, we have "seen" it play out THOUSANDS of times here on SI and other forums, every case is different but cheaters typically follow a similar script.
