My wife and I just had a physical altercation. We had an argument while I was cutting vegetables in the kitchen. My wife got really heated because I was arguing with her. She got in my face and continued shouting aggressively at me . I dropped my knife and started shouting back at her. She suddenly socked me on my ear and caused it to bleed. I wanted to make sure I was not in any danger since my wife was the aggressor, 6'2" 229 lbs, and 2 knives laying next to us on the island. I punched her and knocked her down to the floor. She has a busted lip and bruised cheek. I need some advice. I know she is going to get a protective order on me. Should I do the same?
