Hey Fighter, I did read your story and posts. My WW's A was "over" for about 2 years on Dday.
At this point, she did not have feelings for the OM. I did ask at the time that if I had caught her mid-A, would her response (i.e. wanting R without hesitation) be any different. She doesn't know, which tells me that there is a possibility that her response would have been different.
She does tell me that she didn't want to leave me and my son, the home and life we built, etc. She suffers from clinical depression and at the time of the A, she had lost her Grandma, her dad a month later and a bunch of other "stuff" and she was looking for something positive....enter douche bag OM. He wanted a piece of ass and nothing more, but she talked about her problems with him and he was sooo supportive, blah blah, then once he got what he wanted, he was done with her, until he wanted more. She is so much smarter than this, and admitted to me that if anyone had detailed the same story, she would have told them to run, and yet, she ran right to him.
With your situation, I can understand your W being lonely, and becoming detached with you and finding someone to confide in, but there is NEVER an excuse to cheat, NEVER.
Honestly, the quickest way to push her to make a decision would be to file for D. You can always cancel it, but the shock of the possibility might snap her back to reality. Doing the pick me dance will do nothing but show her she is in control. I can't answer if your wife still loves you or not. Only she knows this. Filing for D might push her to make a decision.
I did a lot of things wrong on and after Dday. I was all over the place with my emotions and anger. You haven't had much time at all to deal with this life changing event.
You can have a look at my WW's profile (only one post - Nedia1978) but gives her side of the story. It reads like a remorseful W but keep in mind, I got the full truth months after she posted on SI, so when I read it, I remember that she was still lying to me. Her A's were not exit affairs. After 2 years, it really just comes down to the OM wanted sex, so did she at the time, so she did it. No thought about me, our family, repercussions, etc.
You WW might have done this as an exit A, in which case, filing for D might not yield the the response you want, but at least you will know where you stand.
Please feel free to PM me and we can discuss things if you ever want to.
