From the article it seems undoubtable that Ella is severely and totally alienated. I think it started out hybrid - he was clearly someone she turned to and had a relationship with during the early stages of the separation. I think it all went wrong when Bianca moved in so quickly. That, coupled with her illness, in Ella's mind meant she was secondary to Bianca in his affections. Then the court documents published emails and videos where Alice came out looking really bad. Alice then really started working on the alienating (he wants to destroy me, look at how he used private stuff you sent him to ruin me and he is using you to do it, you can't trust him, omg he is destroying me and you are helping him, he wants me to die, I'm so scared etc etc etc). Add to that the school debacle and Ioan withdrawing. Total reinforcement.
