So wife is 24, partner is 40, step child is 12.
Behaviour difficulties from a very young age, now quite bad. School have got CAMHS involved.
Wife leaves the room when child enters the room. Will not be left alone with the child due to lies & manipulative behaviour.
When they are together, they argue full scale.
Wife insists that the child is taken to the grandparents for entire weeks if it is school holidays and for entire weekends if she can't be bothered or wants to be alone with partner.
Is quite abusive to the child, swears at her, is clear that she hates the child.
Child is very very difficult to like tbf.
Don't know what the answer is. Where to go, what to do.
