I don’t believe in making children of a certain age doing things they don’t want to do. I think it’s also recognised in the U.K. that a 13/14yo can make some decisions of their own but it is not the case in California so it would depend where they live as to what rights or wishes are considered for the child. I agree best interest decisions are one thing (going to school for instance is usually non negotiable and a best interest decision) but clearly if their mental health is suffering you might need to concede that it isn’t helping your child to keep doing something they clearly hate. I do appreciate that this is entirely Alice’s doing but it doesn’t negate the fact it clearly is having a terrible impact on Ella’s well-being to be such an angry raging aggressive child.
I do think Ella should not be forced to go to contact anymore and that’s cos it’s obvious that it isn’t working and is not safe anymore. Ioan should keep fighting about the PA on her behalf though, and not stop this process as he needs to advocate for the poor kids against this PA. But I am not sure visitation is going to work for Ella. For sure he should keep on getting them into therapy, being present in other ways (phone, emails and perhaps short visitations outside of the home) as clearly Ella cannot be trusted now to be inside the apartment and is putting everyone at risk including Elsie.
I do agree that having a step parent is not abuse, and if you do not like them you should not be forced to have a relationship with them but meeting someone, having food with them etc is not having a relationship it’s just being polite and giving that person a chance to see if you both get along. Ella has never even given B a chance so there is no way she knows anything about B’s character apart from what she’s been told. If this case was E having met B over 6 months and them clashing I would agree it’s not wise to keep going at it, (and evaluate whether it’s your partners fault in this way) but E doesn’t know B and is over inflating and exaggerating what she thinks about B into something outside of what is even remotely normal.
