Yesterday I called her and she said she doesn't know me and I'm not her sister. She said other people (who most likely adopted her) are her family. I told her she doesn't have to return and/or speak to to her "old" family and I just want to form a relationship with her and get to know her better. Then she told me to quit contacting her or she will get a restraining order against me. How can I form a relationship with her if she's pretending we're not related and says she will get a restraining order against me if I contact her again?
