Hi i need advice please. I don't know if i am in the wrong with something my partner does when play fighting with my son. He will tell my son to stop kicking him and he doesn't he keeps doing it and then my partner flicks him hard on his foot for not stopping when he said and my son is in pain crying and then when i have a go at my partner for doing that to him he tells me i need to tell my son off for not listening and carrying on.....i'm always a referee between them and wish he would act like an adult. This results in us arguing and we both swear at each other and dont talk. He raises his voice first though every time and says horrible things in front of our son.
