I should imagine the girls no longer like or respect their father and no longer feel safe with him.
He doesn't apprear to be the deepest of characters.
Clueless and very selfish in my opinion.
He's become a spearhead for all those who advocate affairs and believe children can be discarded and pacified to play nicely with new step partners.
It's shit for the kids, it's shit for Alice but it's great for Ioan and Bianca, the only problem is getting Alice to STFU and get the girls to show Ioan in a great light infront of his new squeeze who incidentally has no experience of childrearing, it doesn't really fit with her programme.
This sort of pile on will make her more ill, she can't take it at the moment, Ioan's in a much stronger possition, why do people wish to make her worse, people have no empathy, all this crap is bravado from her, she will calm down eventually, it will be a long time though because he has thoroughly humiliated her on the world stage and that is something neither Alice or her daughters, I should imagine will ever forgive.
He's a fool.
