Hes mad at me cause im loosed

Yesterday my hub and i were doing the deed, i just gave birth 3 weeks ago. He was very frustrated and yelled at me that im so loosed, it doesnt even feel good. He began questioning me why im so loose, and accused me of sleeping with other guys thats why im loosed. He called me a bitch multiple times. Im beyond hurt and sad about this...do i need to leave?
