Fighting

My husband was helping our child with hw (first time! We usually have it done before hubby gets home) and he was getting frustrated we had been doing it for a minute and he’s 5. He had already had a breakdown of crying and was asking me when dinner would be ready. So 10 minutes later or so plates where fixed and o told them come eat. Then my husband was telling our son he’s not eating until he says this word and he can go to bed hungry and to stop crying and try to say this word. He didn’t know the word and had already told him. this pissed me off so I told him no son come sit and eat. And I told my husband he can try after he eats he needs a break. I was trying to compromise in the moment. My son was feeling the bad vibes and hid under the table crying. My husband then snaps his fingers at me and starts mouthing like your so stupid just shut up. I told our son come eat and gave him a hug and then my husband comes in the kitchen takes his plate and throws it in the trash plate and all and leaves in his car. My son was crying hysterically asking why did Daddy throw his dinner plate away and went and got it out of the trash. Bless his heart. And i comforted him and got him to calm down and eat. Got him ready for bed and etc.

we never have arguments except over our child :( I think he’s to hard on him and he thinks I baby him. How can we as a couple agree and disagree w/o fighting over him?? I raised him alone the first 4 years of his life and we’ve been living together for a year now and it’s definitely been a transition. I’m not trying to disrespect my husband and confuse our son by not backing my husband up but in this circumstance I feel my husband was really out of line with our son. So I felt like I needed to step in.
