Natus,

You are in a hard spot right now. The A has been exposed but as I know first hand, that doesn't mean it has stopped. It could be still going on right under your nose. Has your W expressed any remorse? Has she admitted to any wrong doing? Or is she just wanting to sweep all this under the rug. You've got to be careful about letting her back too easily and quickly. If things aren't dealt with properly, she'll go right back to the A. She works with him so its just too easy.
Definitely detach and don't pursue. Make her pursue YOU. LRT is definitely appropriate once and A is confirmed. You really shouldn't be pulling back from LRT unless you see that the fog is starting to clear, that they are remorseful and that they are willing to do the work to repair the damage they have done. Again, if not dealt with properly, they will go back to the A and even turn this EA into a PA. You've got to be strong and firm in how you deal with this. You did the right thing by contacting OM's W. Set boundaries and expect your WW to adhere to them. Can you look at her phone to make sure she's not emailing/texting/calling OM?
