Personally I don't see Alice moving on from this anytime soon, if ever. We know that she can't afford to stay where they are currently living for much longer, so the impact of the divorce has yet to have its full impact on her life and circumstances.
Of course, this is her fault in that if she had gone through the collaborative divorce, there wouldn't have been over $400,000 and counting spent on legal fees. But, she won't acknowledge that. When she moves to a cheaper neighbourhood, her bitterness will only intensify. It will also be hard for the girls to adjust to the move. So, home life will be difficult for all of them, and Ioan will of course be blamed.
She faces living in very reduced financial straits with no obvious way of improving her lot. She's now 3 years older and her reputation precedes her. It would be a brave/foolish man who would take her on and she's shown no inclination of being prepared to work. And even if she did get a job, she's unlikely to get anything that allows her to live in Beverly Hills again. If anything, things could get far worse as she has nothing to lose.
And as others have said, once the court ordered therapy sessions are done, she will have free reign to undo any progress that was made with the girls. And to be honest, the girls would likely resent Ioan for the changes in their life even if Alice hadn't gone crazy. It would have been hard to accept Bianca especially because they got together so quickly. I'm not blaming Ioan for this as Ella in particular was no longer wanting to spend time with him before Bianca's existence was known. But the reality is, for the girls, they see her as the reason why their father left their mother and them.
I just don't see how this gets better for anyone in this situation unfortunately.
