"She asked if everyone in me realized that if Death actually knew that if I died that we all would die. And his answer was yes."

I have also had this question asked of us... and like you, the answer was yes. my t couldn't understand that. I just simply told her It's a long story.

I do hope you can hold to your boundaries and have a plan B should your mom pressure you. Sounds like good boundary-making in the process!
