Narcissism never occurred to me either about my CG. His therapist brought it up and it was like the light bulb went off! Of course! That is how my CG could abuse all of us because it was ALL ABOUT HIM!
Narcissism will never care about you or anyone else. Until your CG learns empathy narcissism will always win.
I will be keeping you and your partner in my thoughts as you deal with the news of this week. May it be good news.
