I do pray wholeheartily that she DOES give you a fair chance. That she IS willing to try and get to know you and come to judge you for the person that you ARE, and ACCEPTS you. And does not rely on some false images in her head. Just because she knew about his nature does not mean that she fully understands or supports it. Time will have to be a factor. I wish you well hun.
If there is no Heart, the mind will never matter.
