Lindsey--this must be so hard. I don't know what I would do if I was in your situation. One perspective is to maintain the friendship so that hopefully your life can be a witness to her. The other perspective is that what she is doing and promoting is so sick and wrong that it's hard to imagine how a friendship could continue with such a huge discrepancy of beliefs. I don't think I could do it. Just pray about it and ask God to give you the wisdom and strength to know what to do. I'm so sorry that she wasn't more receptive to what you wrote. It was a great letter.
