Under general principles of law, you are describing battery, which is a harmful and offensive contact with another. States typically have a criminal statute setting forth an offense called domestic assault or domestic violence. I did a quick search for the Mississippi statutes dealing with this and I have provided the link below, for informational purposes.
Not legal advice as I don't practice law in Mississippi. It's just my two cents on the facts you describe in light of general principles of law. If you need legal advice, and I THINK YOU DO NEED LEGAL ADVICE, please consult a lawyer who holds Mississippi licensure, not me.
