Not acceptable body

Im 1 month PP and iv managed to lose 40lbs from my pregnancy but my body still hasnt completely toned up and im still covered in stretch marks. My husband is super grossed out by the way i look(which is understandable he has high standards and iv always been slim and never had stretch marks before). Im trying everything to get back to where i was but im afraid my husband will never see me the same. It hurts because hes the one who wanted a baby originally. Iv tried talking to him about it and didnt get anywhere and when i try initiate sex he says he is tired or takes a bath with the door locked until i go to bed. Im at a loss on what to do! How did you get you husband to find you attactive after birth?
