Choco,

To give you some heartening news, the reason your W "cant" tell you the 'truth' as OM sees it is because its not her truth.

She is going to say things to both of you to hold on to both of you.
It will infuriate you, but focusing on things like credibility and how she is not doing what you want her to do, etc is about control and possession. You want her to see you care about her, and only her feelings are going to tell her that.

She is hiding it because she is afraid of the consequences. If she didnt care she would throw it in your face.

At this moment the only thing to concern yourself with is you. You have to get ahold of yourself and make a decision, about what you want. Take the time. Give yourself the space. Your emotions encouraged you to be indifferant. They were wrong. They are going to slap your sensible choc self around without mercy and encourage more mistakes. Dont do it. Sit still.
