Good lord, what an awful position you are in.
Unfortunately I can well imagine it due to the strain on resources and compassion fatigue of mental health resources resulting in sometimes such extreme decisions that seem indefensible from the outside looking in.
Their decision process under stress becomes based on their own bureaucracy and processes vs humanity and any other concerns for people beyond their own specialism…
So don’t rely on them as ‘professionals’ to safeguard your family or care about your children. All they will care about (going off your op) is not having your partner on their books as an urgent person to find a bed for. As beds really are that difficult to find.
However that is NOT your problem, and you DO exist in the ‘real world’ … and need to balance all the needs of your family and not just one single person at the expense of the needs of the two children!
So you cannot let them stamp over you just because they are the ‘professionals’ or they are ‘in charge’. It sounds like they are heading you straight into losing your children and they won’t care at all or take any responsibility for having caused it, the big machinery will churn over you and your family and not care what happens to you all … sorry to sound so cynical there!
But you need to fight back!
I would look at the idea of taking your partner to A&E, and any other ideas of removing her swiftly from the home… in order that you can return your children to you.
If that cannot work then you need to leave your partner where she is (& potentially default on rent/payments there? Tricky and if it’s your own home not ideal).
But the fundamental thing is that you need to be reunited with your children abd in solde charge of them. And children’s services need to be happy with this arrangement and see you as the main parent who is protecting his children.
Children’s services could view the situation extremely badly even though you’ve been forced into this position.
eg not prioritising them or caring about their well-being as you were happy to ‘lose track of their daily needs’ as they are left to take care of themselves sofa surfing at other people’s houses … whilst you continue to stay at the family home, with your partner, focused on your partner.
You have to be seen as a functioning parent who is putting his children first. You cannot be seen as expendable. Or weak. Or not really engaged with your children.
You HAVE to be living in the same place as your children. You just have to be, & that needs to be your absolute priority.
I’m so sorry you are going through this
