Zobird:
Please don't take this as a negative either but Panic Button does have a valid point.
You said: "I believe in second chances and that he will change with help and support."
Forgive me, but hasn't he already had that following his first conviction for violence? Now he's been charged with another similar offence. The reasons why he saw fit to use physical violence are largely irrelevant, he has done this at least twice now, and who knows how many other times for which he wasn't charged/convicted?
What kind of "help and support" do you think could prevent him from doing this sort of thing again? For I'm sure that he has possibly been given that over the years? And if so, it hasn't "cured" him, has it? There is no magical solution.
Unfortunately, the expression "a leopard doesn't change its spots" might be apt in relation to this guy.
I realise that you will in all probability disagree with me but that would be because of your emotional involvement. I have no such burden to cloud my judgement.
Ask yourself this: "Can I honestly trust him never to lay a finger on me again?" Unless you can categorically answer "yes", you should seriously consider your position.
I'm sorry if this has been uncomfortable reading for you and I sincerely hope you make the right decision: for your sake, not his.
