I think no contact is because she knows you see through her bs. Narcissist parents withhold love and attention as a tool to control their children. Like the fear of totally losing a parent and not being loved is enough to shake most people into conceding. It's how they get to continue being awful without having to change. My mom went 5 years without reaching out to me when I told her the way she talks to me is hurtful. My dad bribed me when I was in a tough situation to make contact with her, but I imagine she would have never talked to me again.
I’m sorry! This is awful on so many levels. I sympathize as my mom is the same way in thinking that our relationship is just a one way street. It’s extra hard having a little one when I don’t feel like I can reach out to my own mother.
