Thank you all for your very compassionate and thoughtful responses. They all helped me a great deal as I am forced to process yet more things thanks to my "wayward" - and my need to make myself feel worse because of it.
Five days before she phoned me long-distance (June 5th) - she had also called out to me in a message on "Facebook" (May 31st) because she was sad and lonely. She also called out to others that same evening in the middle of the night on another general on-line support group.
I did not see her "Facebook" message because I was asleep - plus I do not keep "Facebook" up and running anymore since her and I are no more. It use to run always in case she needed me whenever she was away for medical reasons. I was always there for her - and I suppose that she thinks that is still so.
Yes the phone call from her caught me off guard when I heard her voice. It was a long couple of hours since she knows very little about computers and I had to advise her slowly in what to do - plus I was not sure of the source of the problem making it longer than I would have liked.
In pondering what happened with her contacting me via "Facebook" - and also with her computer problem phone call - I can see she is truly messed up "Big Time". I also see how completely selfish she is - worrying only about herself and not about anyone else. That was not how "the old her" use to be - or maybe I really never saw it because I did not want to see it since I loved her so much.
She still is fine with causing me more pain and suffering - as long as it serves her own purpose.
Though at the time I was unaware of her "Facebook" message to me - I was aware she had called on anyone to help keep her company in the early hours on the "Loneliness" group on the other on-line support group. I mentioned it to her during the phone call. I said how can you be "lonely and sad" when you now reside in a place with two other family members - two cats - and two dogs (with one dog being hers which I sent to her three weeks ago)?
I compared her living conditions to mine (now that she and her dog are gone from here) - I told her "what I have here is truly lonely and sad". She gave no response that I can remember.
She suffers chronic pain (24/7) from a near death car accident decades ago - her body is coming up with new medical issues all the time - she has suffered greatly at the hands of other men in her youth and her abusive and manipulative estranged husband ...
... but that is no reason to pass along pain to others - which she seems to do so easily without a thought or a care to the consequences of her actions to others.
I no longer know what I saw in her - I just wish I could forget who I thought she was in my own version from before - and fully see her for what and who she truly is now and who she probably always was - but I was in love and could not see beyond the "rose colored glasses".
In regards to "Facebook" and the other on-line support group - I deleted both my accounts so I will not have to see her messages any longer. In time I will change my phone number but right now I cannot since I am looking for better employment and my phone number is out on many resumes.
Thank you once again to all. This is a horrible situation to have to deal with where strong emotions are involved - our love and our hearts - and how carelessly they were treated by the ones we thought we could trust the most above all.
I shall continue on my path to recovery - and be more careful when the phone rings.
