We have had custody of my step daughter for 6 years now. Before that, we had her more than 50% of the time. Her father and I have been together since she was 1, so I am not the "stepmom." She refers to me as MOM (My other mom). We have always had such a great relationship, until recently. About 3 months ago, we found out that she had been cutting herself. We took her to therapy and thought everything was going great! We couldn't be more wrong! She cut herself "one more time" (so she says) and now is failing almost all her advanced classes, lying, skipping school, etc. AND she wants to move in with her mother because she doesn't like our talks?!!? Well, that is the story this week. It is so hard to believe anything that she says. She lies about EVERYTHING! I am not sure that she can stop anymore. She tells her mother horrible, mean and completely untrue things about us! This whole thing feels like a bad dream and we have no idea what to do! We are having a really hard time dealing with everything right now. Our marriage and relationships with our younger children are being affected in a negative way! The therapist doesn't think her moving in with her mother is a good idea. We are so torn! We only want what is best for her! If she is going to improve in school and in her mental state by moving away from us, then we will do it! I think that she will get over there and realize that she screwed up and that the grass isn't always greener on the other side. My husband agrees. We had decided to do a trial run and let her finish out the school year at her mothers. If she improves and everyone is in agreement, then she can go to high school there. If she continues down the same destructive path, then she will come back home. Now we aren't so sure anymore :( Any advice?
