I have 2 Step Daughters, 18 and 16. I love them like my own children and have had a great relationship with them for almost 12 years. The 16 year old has always been especially close with me. We are a lot alike. About 5 weeks ago, out of nowhere, she completely cut me off. She will not speak to me, text me, see me.....nothing. It was like a light switch. She went from her normal loving self to completely icing me out in a split second. I have no idea what I did. I have tried to reach out to her, but I can't get any kind of response.
