Sounds good, and I agree with her, she is not your xwife yet. But she certainly did not like the sound of it. You seem to be getting reaction from her, and that is a good thing.
She may be realizing that you were nice to have around at times like this.
Also, be nice to her, like you would a friend, but do not fall into that carring roll. She chose for you not to be there, not you. I like your plan for the funeral.
