Interesting update. I wouldn't offer to talk, because she might see this as pressure to tell you her personal stuff (and yes, she definitely owes it to you, since you are her H, but she doesn't see it that way right now.) However, if she contributes info, such as the "being wrong" statement, I think it's a good idea to ask questions that show you are listening. Paraphrase what she's saying so she feels you are paying attention, and never judge her feelings or offer solutions. Just let her talk, nod, and paraphrase.
Good luck with that. I still see things turning around for you guys. Keep up the great work, and keep meditating...
