I must admit I am confused with how one is to detach. I know some people indicate that I should not be rude or harsh and others say I should.
No treat her like you would a good friend or someone on the street. Do not be rude. Be kind. They do remember how they are treated when they are in the tunnel. That does not mean that you should not maintain your boundaries. You must stick with them. Try to re-read the detach link for additional help.
