I also know this is dangerous territory for me. I have strong tendency to need to help and heal and I have lost myself entirely in a narcissistic relationship in the past. I'm worried about my capacity to handle this and so ultimately think I will have to step away. I'm scared to do that now whilst there is no one else there fore him.
So before you came along who was
“there for him” who was his care taker before you and what happened to them?
Maybe you are not currently getting lost in a narcissistic relationship again but you are getting lost in a codependent one.
