I manage a domestic violence service in Surrey. Whilst I am unable to assist direct due to location, I can signpost you to local Wandsworth services. As per a previous poster, I suggest you have IDVA support for court attendance (Independent Domestic Violence Advocate) as these will be trained specialists who certainly have understanding of how 'normal and nice' a perpetrator can present themselves in public and why you may feel scared.
Suggest you contact or visit: Wandsworth Domestic Violence One Stop Shop
