A bit of an update on the situation.
So as predicted the ex has made it difficult to see my partners son since the CAO was dissolved.
We've seen him 8 times since April.
There's been some weekends we're due to see him and she'll say "Son isn't well/he wants to stay with me/he has plans".
On one occasion she even admitted she lied about him being ill as they went away for the weekend.
Things escalated further over the summer and she threatened to call the police when my partner turned up to see the kids as he couldn't get hold of them
She then did call the police.
They came round for a chat a few weeks later. It was an amiable policeman who said he had to speak to the kids but wouldn't go further as it was a civil matter. He also supported my partner going round the exs house if he felt he had to do a welfare check.
Fast forward a few weeks. Haven't seen son in almost 4 weeks. The ex either ignores my partners text or replies in rages. She says it's too late for dad and daughter to sort their relationship and he's not welcome at the house as he's invading their 'safe spacw'. She just says the kids have their phones. But they never (daughter) or rarely (son) reply.
Now we've received news from a friend (daughter goes to school with son and they're best friends) that son has a bruised face from his sister lashing out, he fainted at school and is struggling with his eyesight.
Where on earth do we go with this second had info? When similar has happened in the past and my partner spoke to the schools no-one seemed to give a blind bit of notice.
The children are clearly suffering in that house but social services/cafcass/psychologist all deemed mother wonderful.
The woman is not right in the head.
