We can't read her mind but that's what I would have been thinking. And as gogofo's W told him, "there was never one big issue or event, it was multiple little things that piled up over time."
In an honest, healthy R, she would have told you what she needed but you haven't had a healthy R in a long time. She's done, you're the one who wants to turn things around if possible.
So you have to do the work.
How might you handle things differently the next time she says she wants to go to church at 0800?
What might you say to her now to find out what she needs from you in those situations?
This gets back to that divide of responsibilities in your household. She's no longer happy with that set-up. How can you show her you're hearing her and understand and that things could be different?

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
