I haven't kept firm tabs on this thread but Alice needs to STOP using Twitter as her counselling sounding board (and with Alice, it seems, she only highlights echo chamber replies - so it isn't really counselling either - you also get constructive criticism when seeking professional help). Which is actually what she sorely needs.
If Ioan DIDN'T CARE about his kids (she says its twice a week for two minutes, but is it?) - he would SAY NOTHING, DO NOTHING - he'd be GONE - like my father and countless other deadbeat dads. How does she KNOW that he doesn't care about "our kids' hopes, needs, problems" unless she's listening in?
Being isolated is a witch and I absolutely understand how desperately sad it must make you feel, when there's still love there and your partner is gone - when there's financial pressures, when you're in emotional freefall (Alice is, maybe her kids are because they're picking up on mum's energy?) but if Alice truly is the "alpha" she proclaims she is, she will stop the nonsense and take the responsible parent route.
I don't blame Ioan for not trusting her, she is a classic over-sharer who lacks self-awareness, boundaries and is led by her emotions. Not a good combination.
Most TMI people I know online are teenagers/in their early 20s, but most who live their lives online tend to gain perspective as they become more settled/responsible. Ie, they become more mature. Alice, it seems, has never learnt this or evolved in this way.
Edited to add: I have seen older posts on these threads when their marriage was seemingly going quite well, and Alice seemed to delight in making Ioan cringe by uploading pictures/photos he may not necessarily want fans to see. Of course if it's "banter" and both are able to laugh about it, fair enough. I suspect this was just one bone of contention between them, as IG seems very private. It reminds me of Russell Brand's notorious "just woke up" picture he posted of Katy Perry (which I thought was a particularly cunty thing to do).
