Yep. I know exactly what you mean. Many times, what the former Mrs does is of wonder to me. Sometimes she says what she is doing; other times, no. She seems to be hiding stuff from me. The difference is that she isn't working under the guise of "fixing the marriage."
One thing is for sure. You are giving your best effort here. We can't control others. At the end of the day, all we can do is look ourselves in the mirror and know that we were true to ourselves.
