<human>: Could you distill the essence of the text into 1-3 sentences?

A woman I dated for two years sent me an email this morning. I ended things with her about three months ago.

She saw a girl's post on Facebook in which I was tagged. In her email, she said that this tore open her wounds from the breakup, that she wasn't ready to think about me dating other people.

We had been texting and seeing each other occasionally since the breakup, nothing romantic. Now she wants to go 100% no-contact, and has asked me to unfriend all of our mutual friends on Facebook. I guess this will guarantee that she does not see or hear anything about my life going forward.

I have a history of burning bridges at the conclusion of relationships, and I lack friends from big chunks of my life, e.g. college. I would hate to do it again.
<bot>: Ex wants me to unfriend her friends on Facebook so there's no chance she finds out about my personal life. Is this insane?
