Abandonment is a big sign the S has guilt and can't handle facing their S for whatever reasons: OP/anger issues/addictions/MLC, etc. etc. Unfortunately, the S has left or wanted to a while ago and the hurt S just was in the dark. It's sad but the fact. How the other S can do this is a mystery to me, but there has to be a mental blockage with denial, delusions and many times amnesia. DBing friends: the only thing left is concentrating on ourselves and how we can go on and praying to God that somehow the S wakes up before we move on for good, which has happened to most of us.
