This is a fair assessment and, as always with human beings, it's a lot more complicated than it looks. I haven't done a full diagnostic on her, but the pattern is familiar enough to me. She has been down this road, and she will continue to travel down it until she addresses the underlying reasons for going down that route. Whilst it's fair to say that she may not be able to uproot two kids, we can presume she has already put the kids through a separation from their father (for good reason) - but has since entered a new relationship that also turned out to be disruptive and problematic. This relationship did not need to be entered and that period of self-reflection was too short, particularly since there were two children to consider as part of her process.

We have interpreted Dr Phil differently; he's bang on about past behaviour being an indicator of future behaviour and there should've been more questions about whether moving in with this man was the right decision. Unfortunately it wasn't - and she needs as much compassion as he does and very much a way out, but she does also need to take some responsibility (particularly with the children as part of her choices) to get at the root cause of this dynamic. I would suggest it's likely related to early years trauma and finding comfort in a lifestyle that constantly shifts. Some people are comfortable lurching between chaotic situations - even when they express exasperation. What people DO is a far better indicator than what people SAY. You may be right, she may be spiralling - but based on your research, this isn't the first time and that throws up additional questions that need to be asked.

I don't necessarily think she's trying to humiliate him - as he probably doesn't read the blog... but he might and I don't know enough about either of them. I just know they need to separate and neither of them needs to be given a hard-pass on self-reflection or responsibility.
