Some days are better than others

[EDF]

I'm really really considering exposing my W's EA soon - letting her know that I know. I'm aiming to get another phone coach session ASAP, but I could really also use a sanity check from board members.

Quick recap:
BD/ILYBINILWY/Asking about an Open Relationship: 4/1
Snooped and learned of EA (and pursuit of PA): 4/7 but I have not confronted.
Started DBing and GALing around 4/7 too.

So, I started reading ... last night, reading select chapters and it's really resonating with me. And naturally there are big similarities with elements of DB and nuggets from vets like Sandi2.

I feel I've been doing a decent job DBing and GALing, and there have been a lot of positive changes with WW: both in her suggesting we do things together and enjoying herself, apologizing about making me go through this, and in her noticing and complimenting the positive changes I've been making. Almost all interactions are initiated by her. I set a boundary about not being ok with Open Relationship and marriage being a commitment and monogamous. I feel like she might be coming out of the fog based on the positive changes, and her online contact with OM has seemed to be getting less frequent and often platonic (last contact 5/7, and frankly it seems like OM with wife+2 kids may be avoiding her) but she's still been sporadically pursuing.

So on the one hand it seems like things are improving and I don't want to jeopardize that. But at the same time the consensus from vets here seem to be that she won't truly be capable of re-entering a healthy relationship with me until she has her own reckoning, snaps out of the fog, and chooses to really commit to winning me back. Either way I'm not interested in letting her back into the marriage unless she truly commits and is willing to put in the work, but I'm not sure which path gives the best chance of success.

Any thoughts? Am I crazy to confront her at this point when things seem like they have been improving, or has it all been "cake eating" and now is the time for me to Expose and lay down the law? (Previously phone coach had expressed concern that exposing may make her more focused on the anger of me snooping rather than her own actions.)
