I would just wait. She's probably in that stage where she would just scream in your face, "SEE THERE! I TRIED TO TELL YOU! I KNEW YOU WEREN'T LISTENING......YOU SO & SO! .........Yeah, I think I'd wait on that one.
Here's the thing, and it's kind of sad. Even if you got down on your knees to apologize, I don't know if she can get over it. At least, not right now, b/c of the wall of anger. That is an inner work for her. I hope she can come to terms with it, b/c bitterness leaves a mark on the person, almost as if they've been branded.
When a person learns something new, they are often eager to apply it or share it with their spouse. However, when you have a wayward spouse, your road and their road is not running parallel, at the moment. Your timing and their timing is not the same. That's not to say the day will never come that you will be able to talk about it. Hopefully, you will know when the time is just right.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
