Does a step-parent have the legal right to spank a step-child?

Question Details:

My husband has spanked my two children. I was not in disagreement because I know he loves them and they were acting out in front of our son together. My children's father came and is threatening to call the police if I don't divorce him. I have asked him to leave just so I don't lose my kids. My kids told them that they didn't want to live with me if he lived here but now are saying they didn't mean to say this. What are my rights? How long does he have before time limits are out in Ohio to file charges? The son was spanked a year ago no marks; the daughter last week no bruises. Important Notice
