Earlier my son was playing with his toy fire truck and pushed it and ended up running into my husbands foot

My husband threw the glass cups that he was holding to the sink not in it but to it. Than yelled sorry screamed at my son who is 3 then picked up his fire truck and threw it to the wall which has a mirror on it nearly broke it my son ended up crying of fear I picked up my son and ran into my sons room in tears. Locked the door. Few min later he comes to knock on the door and wants in. My son unlocks the door my husband apologizes and acts like nothin happened. He then asked me to make him lunch. Of course I do cause I didn’t want him lashing out again... I’m scared for my life and my son. He claims he don’t have a problem he thinks anger management won’t help but what happens when he has an even worse fit. What if he hurts us what if he puts his hands on us. I have no job no income what so ever I have a house that’s in my name that my stepdad have to us but put it in my name but due to having no job I can’t kick him out cause I can’t afford all the bills we have and nobody can watch my son for me. So I’m honestly stuck.
