Trust is something that can always be rebuilt, just like a M. I'm not saying it's not an issue, it is right now. I just don't want to see you get so caught up in the bitterness and anger(feelings) toward W that you lose focus of what you have to be doing right now. Your both going through a journey right now, one that doesn't make sense to you. You just have to focus on yours and not hers. If she comes out of it later on and realizes her mistakes, wouldn't you still want the love you shared with her? Don't plan or expect this happening, just don't slam the door on it ever being possible because your angry right now. It would be rough to forgive the things she had done, no one is saying it wouldn't be and maybe that's not something you can do. It's up to you to decide.
Just remember this. She was angry/resentful at you and wanted something better so she left the M trying to find it. You didn't approve of what she did then. If she wanted a relationship later and you left that chance because of anger/resentment, how would you be doing anything different?
Things will still play out how they play out,you just have to decide how your part will work when it comes to it.
Accept what is, let go of what was, and have faith in what will be
