WH, So sorry for you having to hear this. What rubbish!
It might help you to know that my H's OW masquerades as a relationship counsellor. Just imagine the sort of advice this predator gives to women who seek out her advice! She is a divorcee who has pursued my H relentlessly, telling him that children are 'resilient' to divorce and offering the services of her lawyer.
I realise that she represents the worst-case counsellor scenario, but it just goes to show that counsellors are only (inadequate/interested) human beings, not necessarily knowledgable 'experts'.
