Your looking at it all wrong. There will be justice, but it will happen when you stop letting her control your emotions and are able to see how great you can live with or without her.
"she will live with the OM in peace and happiness"? That's a fantasy world that cant survive. Its only good for right now, one day it will shatter.
Its fine to feel anger, its just one of the emotions you need to get through. It will come and go, experience it and don't fight it. Just make sure you don't react to her when shes around.
An alternative way to look at this.(Only suggesting it because its very similar to what my IC has told me)
If she does stay in this fantasy world forever and never sees the destruction shes done to you. Would that be so horrible? If that's who she really is, wouldn't she be doing you a favor by letting you go. Your in a win-win situation and you cant see it. She recognizes what shes done and you two work on rebuilding the M into something better, or she releases you to find someone worth your love. Yes time is a big factor in this, but until another person finds her way into your life, you don't need to make a decision anyway on moving on. Either way, your path right now is to still focus on yourself. All the advice you already know, just have to keep doing it.
Might be time to find a good GAL activity to get you out of your comfort zone and experience something new. Something fun and exciting. What do you think?
Accept what is, let go of what was, and have faith in what will be
