Feeling like I have two choices...read the book, begin DB right away. And the other choice, confront her now and start distancing.
Im not really sure what you mean by "confront her now and start distancing". I dont really see that as a plan. Confrontation is one thing, but it doesnt necessarily do anything without a plan to bac k it up.
I'd recommend you start by reading the book and starting at step 1. Then we can talk more clearly about your "options".
