Lee... Have you not listened to anything anyone has told you?
She doesn't take your calls... why are you calling her? You try to get her to discuss the "next step"... more pressure. You tell her her actions say she is done... why are you talking about that?
If you want to be done, keep doing what you are doing. You are pressuring her still, pushing her away as fast as you can...
I still don't think you've read the book. Read it. Not bits and pieces. Don't try to pull out the things that fit the way you think things should be.
It may not work, there is no guarantee at all. But DBing correctly will feel "wrong". It goes against your instincts. But, look where your instincts have gotten you. Do you think they are helping?
