She told me because she said "I always want us to be 100% honest and open with each other. i know you have trusts issues to the nth degree and I always wants to be completely transparent. Maybe if you know that I will never lie it will be a beginning for you to trust me."

So while it bothers me a bit, especially her bringing up the article about my grandma and then wanting to talk about it(very small town so it made the paper that her 6 year old granddaughter found her on the couch passed away), I actually respect that she was honest with me instead of hiding it.

I also was a bit offended but after reading responses here I no longer am. I had never thought about that she deals with people who are delusional or suffering from psychosis.
