If she wanted to come out looking good in this, she should have done the following (the most important steps are in bold):
1. After the release of the joint statement announcing their split, made a few social media posts saying that she was in a situation she never expected to be in, but she was going to embrace it and forge a new life.
2. Perhaps given one/two interviews on TV, but framed it in a "there is life after divorce when you're in your 50s" way, and not said a bad word about Ioan.
3. Engaged in collaborative divorce.
4. Not alienated her kids.
5. Not gone on Twitter and spouted venom. She therefore wouldn't have got the DVRO several months later. She would have recognised the role her social media addiction had in the downfall of her marriage, and she would have sought treatment for that.
6. Not drunk excessive alcohol, and kept her weight in check. Started an exercise regime and channelled her anger and sorrow into this.
7. Grown her Instagram following by posting positive things. She has a large following and brands would have sponsored her to do posts.
8. Not forced Ioan to reveal his relationship with Bianca. Tattle found out about that (which is how Alice found out about it), so the tabloids would have picked up on it eventually. Ioan would have looked so bad as Bianca is so much younger than Alice (as it stands, Ioan did end up looking bad, but Alice had already acted in such an unhinged manner that plenty of people saw through her and didn't blame him).
9. After the relationship reveal, Alice then could have given a few more TV/magazine interviews, where she said that it's tough being replaced with a younger model, but she was here to show women in her position that a good life was possible after a divorce. Crucially, she wouldn't have trashed Ioan or Bianca, so she would have looked even more amazing.
10. She's good at writing, and with her contacts she might have been given a column on how to thrive after divorce in your 50s.
11. She might have leveraged this into a media career, appearing on chat shows, or shows like The View/Loose Women.
12. She would have therefore ended up with a better settlement from Ioan, and his goodwill. There would have been more money to go around. They might have been able to have a cordial, or even amiable relationship. Their daughters would have been happy and would have adjusted to the new dynamic and housing situations.
13. She would then perhaps have a career as an influencer/talking head/writer, which would have still given her money and invites to showbiz events (which she craves).
14. If she didn't have a media/showbiz career, then she could have looked at becoming a languages tutor, an acting coach, or many other jobs which don't involve her working in McDonald's or Home Depot (Alice seems to think there's only two jobs - acting, or working in these two stores). She says she's bedbound, but she could have worked from home as a tutor or coach, and chosen her hours/days to work.
15. She could have written a book about her experience, but it would have been a self-help book/part autobiography on how hard it was to conceive in her late 30s/early 40s, her IVF battles, her difficulty in finding work as an older actress in Hollywood, and how to navigate a divorce when your husband leaves you after 20 years for a younger woman. In this book, not once would she have trashed Ioan and Bianca, or revealed any secrets. The divorce would be framed as a "it happens, let's move on" type of thing.
16. She very well could have met a new man by now, someone who was impressed with how she dealt with the divorce, and also how good she looked for her age.
Many of the above steps would have required Alice to do some serious introspection, and for her to realise that her behaviour was the problem. Unfortunately, she is incapable of this.
She's completely fucked everything up, for herself, her daughters and for Ioan. She's made Ioan spend hundreds of thousands of dollars that he didn't need to. She has a DVRO against her. She's mentally scarred her daughters. She's engaged in a wicked and frankly bizarre plot to get a restraining order out on her husband from his own daughter, and to get her husband's girlfriend deported.
And now she has almost nothing, and her reputation is in ruins.
