我也動過手

But I was not arrested. Instead, I was ordered to leave home, separated from my wife, until the next day. The next day, in court, I asked the judge to let me back. After getting my wife's agreement, the city attorney gets the order from the court to let me go back home.

Your case, if you want your hu*****and back,

1) bail him out as soon as possible
2) find a lawyer to represent him in court date, about $1200
3) explain what happen to the city attorney, and your willingness to get him back. City attorney may recommend to the judge a lessen punishment to him, e.g. 婚姻谘詢服務.
4) Both or only your hu*****and gets 婚姻谘詢服務. I attended something like that 2hr a week, for 6 months. It helped me.

Otherwise, if you don't want him back, do nothing. Let him be charged the most serious possible. Then file a divorce. He will not get the child(ren) for sure.

P.S. 夫妻爭執,在所難免. 司法介入,於事無益. 婚姻谘詢, 幫助更大. Now my wife and I still 湊合著過. We have two kids.

Only two options:

Adapt or Away -- change yourself (for both of you) to adapt or walk away

Good luck.
