Hi confused, basically, the offence of common assault can not go to Crown Court, jurisdiction of advocacy for this offence remains in Magistrates Court, which is known as a Summary only offence.
Unfortunately, the modern police have changed for the worse (because of lefty type bureaucrats). I fully recommend that you comminicate with ncdv.org.uk and discuss your situation with them. Its free, its good and can even get free injunctions in cerrtain situations.
Let me know if you need help I will try and advise.
