Domestic Violence

Just wanting a little bit of clarity.

My ex was charged with two counts of assault and a strangulation on me last year. He was offered diversion (counselling sessions) and that was it, has been wiped off his record. Of the few lawyers I have spoken with, none had heard of that charge been given diversion. I know the police didnt submit the correct paperwork when it went to court, but surely that wouldnt matter. I am struggling to get over as i feel like that’s incredibly unfair. It was his first charge. Why does he get to live his life but i have to suffer with what he did to me.
