Ripken - LRT with a WW and divorce filed #3

[Ripken8]

Really confused as far as what to do and how to proceed. After reading tenbook's situation, I'm unsure if my wife is a WW or going through a MLC. She's 33, turning 34, so not sure if that;s too young for one, but here's a rundown of our sitch and her history:

-Dad abused mom growing up, got divorced and WW had a horrible relationship with father, who emotional and verbally abused her. Cut him out of her life at 18
-Had a relationship with an ex that ended poorly at 18, he dumped her and between him and her father, she ran to Omaha
-In Omaha, was in a job for 6 months she hated, felt lonely, didn't know anyone and met me, we immediately started dating at 19 and moved in together and within 3 years were married with a kid
-7 years into our marriage we had been in and out of conseling and she admits she no longer loves me and is having an EA with her ex when she was 18 - I move out of the house, she said she's filing for divorce, but never did
-Her mother and sister are diagnosed with Huntington's disease, a rare, incurable illness that leads to dementia and early death. WW has a 50% chance of having it because her mother does and if WW has it, each of our sons have a 50% chance. This leads to a lot of guilt and risk of suicide among people facing this. Depression is high.
-Her mother comes to live with WW and is so far gone, it's hard for WW to deal with and take care of her
-3 months after moving out, her EA dumps her and she runs back to me and starts initating sex with me and we work things out and I move back into the house, her mother moves back home to Wisconsin
-WW wants to gets tested for disease, but is too scared to and we sweep under the rug. We do not go back to conseling to fix any of the problems that initially occured
-We spend 2 years happy and agree to renew our vows on our 10 year anniversary last May
-JUL/AUG/SEPT she is off. She starts smoking, complains about how she hates work and is unhappy and doesn't know if she's ever been happy or ever could. She goes through a big depression
-OCT she claims the reason she has been depressed is she needs to get tested for Huntingtons and to stop living in fear. She schedules her test for FEB/MAR of 2015
-End of DEC she tells me she loves me, but not in love with me. Unsure if she wants a divorce
-JAN she admits to going on a date with OM, but that they are friends
-JAN/FEB she continues to go out late with whoever, unexpectedly and wants nothing to do with me. Said she needs space and is unsure what she wants to do in life, whether to go back to school, quit her job, unsure about anything and just needs to be free and find herself. She also said she is unwilling to do counselling and is constantly triggered by me and past hurt. She no longer feels she can get past the hurt, trust me and risk getting hurt again
-MAR she gets her results. She does NOT have Huntingtons. She continues to tell me she is unhappy. Apparently FEB (at the latest) is when she started her affair and hid it from me
-APR she hides money from our tax return, files for divorce, drops the bomb and finally admits to the affair

Overall, her MO is when things get tough, she runs and just wants them to be over. She has essentially cut her 2 sisters out of what's been going on for her and surrounded herself with OM and work friends she has known less than a year, who have no idea about me or our relationship, only people that would support her affair and moving on.
-Our joint therapist over the years believes WW suffers from PTSD with me and past experiences with her father. Until that's treated, feels WW will always feel unhappy after 2-3 years and the pattern of running continues.

I have done the no OM speech, given a boundary of not being able to be her friend and had things strictly communicated with me lawyer. I realize there's nothing I can do to change her, until she decides she wants to work on her.

What I don't know is does this sound more similar to MLC or WW? If one or the other, how should I react? From what I've read MLC is more about understanding her hurt and not trying to create more pressure, playing the long game - if you can handle it. And WW is standing your ground, setting boundaries and gaining respect.

Based on this, what do you guys think? I'm second guessing everything now. Any other questions about my sitch I can clarify?

Sorry for the long post!
