I would hope he is looking at a jail term, but without more information as to charges we can't say much.
I am struggling with the 'time line' here, in the first part of the question you talk about what happened up to March when he 'moved in with another gf and got found guilty'. Then you suddenly say 'in a&e the doctor thought I had a fractured skull'
We need the whole story from the beginning in the order it happened without jumping from one time to another.For example '' You say he didn't turn up for court in March'' and then in the next line you say ''he got found guilty'' when and where did he get found guilty and of what offence? How and when did you get the suspected fractured skull ?
