She made the classic "I just want us to move on and forget this" comment.
Yes, it is classic, and that probably has a lot to do with the real reason she doesn't want to deal with a MC. She just wants to sweep it under the rug.
I probably don't need to warn you that with the attitude she currently has, her transparency isn't going to last very long.
If she should repeat her statement about knowing what she needs to do, why don't you ask her what that is? If she gives you any self-centered response, then ask her if she knows what you need? Check her attitude, b/c that is a measuring stick that tells you where she is in the relationship. If she's haughty, resentful, agitated and doesn't want to discuss a plan to use, avoidant, easily irritated with your needs from her, etc.......then you will have a good idea how much she's really piecing.
Remember, whenever she says things like she just wants to move past it.......tell her, "It's not that simple anymore".
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!
