You don’t want to. You think it’s embarrassing. You are scared of what he will do after you call. But you have to call the police if your husband threatens you physically or slaps you, kicks you, punches you, knocks you down, pushes you so hard you fall down, hits you with anything, chokes you (a little or to the point where you are blacking out), drags you down a flight of stairs, tries to throw you out of your house when you are not dressed, ANY behavior that is scary or hurts you; ANY behavior that is physically intimidating, REQUIRES a call to law enforcement.
You MUST document the abuse. Otherwise, when it escalates to the point that is untenable (and it will) you won’t have any evidence to provide to a judge to prove you NEED the protection of a Temporary Restraining Order to stay safe.
