Most Helpful Girl
My husband and I play fight, on rare occasions he has accidentally hurt me. If he thinks I'm in any pain he stops. If I say stop or "ow", he automatically stood and asks if I'm okay. Once or twice he's made me cry a little, he stopped and hugged me and apologized like crazy and covered me in kisses.
You need to tell him that when you say stop that he needs to take you seriosuly and stop because when he doesn't stop it scares you.
