Thanks for the kind words Sandi though I am not sure how much of a role I have played in not seeing her. Not contacting her, that is something that is within my control.
In the book, it says to try things and wait to see if there is a change in 'behavior'. How can I tell if this is having any impact without any insight into her life? Or does it even matter when going dark? I blocked her on FB a while ago, I literally have no idea what is going on in her life. Would her contacting my sister and sister in law be consider a change in behavior? I don't know, seems pretty random to me.
