I am being silenced

My X did not return my daughter today. I took down all the posts because I don't know what is going on. I know she is confused. X told my husband Annabelle didn't want to come home until Thursday but she did not communicate that to me and I have again been text begging him for information on what is going on. She always comes home on Tuesday. Because there is no communication and I am being alienated. I don't know. I am working on trying to get her a therapist. I am just worried and I can't sleep again. Her text communication was odd. She has no problem telling me when she is angry but didn't text back when I asked if it was true she didn't want to come home until Thursday. It was as if someone was standing over her. I just texted her I love her and left it at that. I have been dealing with this for two years now but this is the first time he has refused to return her. I am just so tired of this. I am just really worried. I can't read or sleep.
