Eden,
My heart breaks for your situation my man. So much progress, and she just ends up doing jumping jacks in the quicksand because its familiar. Her mental state is a huge factor in this. What she has done (right or wrong), is familiar to her, and comes with ready mix just add meetings and stir...."friends".
Of course reality is very different from this world, but she is foregoing it.
I personally agree with the advise to love-bomb her on your own. Let her bring it up. Be a great husband. Smile, joke, love her, and be open. Respect what she is telling you, keep your anger in check, and the opportunity WILL arise to talk with her some more. When it does, appeal to what you already know, and don't unload the barrels on her.
I don't really know you guys so who can say what will or will not work. But if you love her.....then love her. Love her the same way you would if she was dealing with an illness she had no control over. Does that make sense? In the mean time, if you are happy as an introvert, no problem. Make an effort, go out with her, and make plans. Go out and do stuff. Movie, walks, take yoga together. Ha!
