ABH will i get off with the crime?

[jay555]

I hit a girl after she was giving grief on a night out. I then hit her again when i seen her on another night out because again she was giving grief and i recalled her pulling my hair out. I then hit her a third time no so long back, she punched my best friend - possibly thinking she was me - so i ran after her and laid into her. Ive been charged for ABH what do you think the chances are that i get off with this crime?
