How to approach W about OM

[OfficerInNeed]

A few more questions I have...
- Do I now start to push for separation?
- She has not wore her ring in over 2 weeks. Do I now stop wearing mine?
- Do I still continue with the LRT? and how do I implement it in such a situation.

It is tough to sit back and not speak up but anytime I do she brings up the past or just shuts me out. I am afraid no matter what I do it will simply push her to pursue OM more. If I carry on with my own life she then thinks I no longer care and so she will look to him for support once again. If I express my feelings she gets annoyed or defensive and turns into a monster. She has no where else to go for now so we are forced to live together. She also refuses to sit down and go over the paperwork when I bring it up because that is all she wants right now. She just tells me "I will take care of the paper work and serve it to you" rather than acknowledge my efforts to handle this like adults.

As I had mentioned despite the past month or being an emotional roller coaster, up till yesterday it seemed we were co-existing quite well, she spoke future tense and all was well considering the situation then she ended up doing this.
