My .02
I get why you slapped him, I understand that rage. In the heat of the moment I also understand not caring about going to jail. I PROMISE you, you do not want to be charged with Domestic Violence. That charge could f**k your life up so bad you will wonder why you didn't care. Nevermind the thousands for your attorney, the possible protective order that will leave you out on the street, the hours of classes you will have to attend and the sentence you will be given - the label and arrest stay forever.
You got lucky last night that your husband didn't back hand you into the next state and that you have all your teeth this morning.
Its just not worth it. If this is where you are at mentally please get out of this situation. you don't deserve the verbal abuse and I get the slap, I really do. You poke the bear long enough eventually the bear is going to roar.
