Please take a look at the advice and suggestions I made to you via waterlego on page 28.
Have you made contact with your useless CAB solicitor?
When will your application for an occupation order be made/heard?
Have you received feedback from your domestic violence counsellor following last week' MARAC meeting?
Have you approached your dcs' Headteachers or their GP with a view to obtaining appropriate therapy for them?
You should be aware that no reputable marriage guidance or other counsellors will engage in joint couples counselling where one party has inflicted violence on the other and I would suggest that you appraise Relate of the facts of the matter if you are still misguidedly giving consideraton to seeking assistance from that organisation.
The stark reality is that your h inflicted serious violence on you in front of your dc and he needs to attend a domestic violence perpetrators programme before any consideration can be given as to whether your marriage is worth the cost of the licence.
I am extremely concerned at what appears to be the failure of certain authorities and agencies' to put appropriate measures into place to support and protect you and your dc.
Unfortunately, IME this is not at all uncommon and, until you encounter a professional or experienced dv worker who knows their arse from their elbow is capable of doing the job they are paid to do in a responsive and sensitive manner, you are going to have dig deep into your inner resources and start taking certain inviduals to task to get the help you so urgently need.
As it would seem that waterlego does not have time to advocate for you, do you have anyone else in rl that you could entrust with the task of raising hell making calls on your behalf if you do not feel able to speak up and out for yourself at the moment?
