I agree with Sandi. Some WAS find the board and get super pissed and its a disaster. Others find the board and use this as a tool.

If she did find it, she used it as a tool to look in your mind and give you want you want to make your feel comfortable in the MR. That's a good thing.

Like Cbtdad asked, she clearly wants you an the M. What do you want?

Also, have you made changes to address the insecurities and issues with the MR that she had?
