hi hun. i went through the same thing with my husband and his ex and son,cafcass only spoke to the child in the presence of his mother and she had primed him on what to say,my children and i were interviewed which felt like an interagation.my husband was only allowed to see his son once a fortnight for a hour at a supervised contact
center. the ex or myself wasnt allowed in so i waited in the car while she and her family verbally abused me, the family court dragged on for 3 years when eventually no matter what the courts said the ex decided my husband couldnt see his son any more, sadly that was 5 yrs ago, my husband still regularly sends gifts and money for his son but has had no contact, needless to say hes heartbroken, i wish you well hunnie and good luck for the future.
