Getting physical... In a bad way

My husband and I had a really horrible argument yesterday to the point where he was pushing me around, holding my neck while pushing me back and braking my wrist. I don't know what to do at this point. We got married 4 months ago and we have a long story about our relationship, a good story before we got married. After marriage everything changed and now he made this excuse of not being patient with me anymore so now he pushes me around leaving bruises. I hit him too, because I'm tired of these situations. It's getting worse and worse each day. He apologized after for his actions and he said he needed tocalm himself down by playing video games and laughing so hard all night long. Because of this I don't think he was sorry at all, because this is not the first time. I know he looks for excuses to play video games because they are his addiction. Everyday is the same routine, work and video games or Netflix. That's it. I talked to him, cried, begged, asking him to do something else, at least pick up the clothes he leaves on the floor, but no. Nothing happens. I don't know what to do. I pray to God almost everyday to show me the way to change both of us. I'm far away from home and friends and I really don't know many people where I am now. It hurts... All of this. I'm lost...
