How does your husband deal with tantrums?

Yeah, both him and my daughter. I am really really struggling right now. She’s two, so she has tantrums and whines and cries just about all day long. It’s hard. But I just don’t agree with the way he talks to her and so Ive started saying something and now we just fight constantly. She will start whining and he will say “ Harlow, I’m going to scream at you if you don’t stop” and then she will whine again cause she’s 2 and it’s normal and she obviously didn’t understand what hw said and he will just scream at her “ SHUT UP, lay down and shut the fuck up, what is the matter with you” so I step in tell him “ she’s 2 this is normal behavior , you are being verbally abusive. Telling her “ what is the matter with you” drew the line. Making her believe her normal behavior for a 2 year old is out of the ordinary which it’s not. He’s a good dad he will take her places and play with her and she loves him to death. I just cannot handle the way he “disciplines” her. When I say “ she’s only 2 she doesn’t know how to handle her feelings” he think I just making up excuses to baby her and spoil her. How do your husbands deal with tantrums. I’m going to end up leaving a 10 year relationship over this cause he will say “ I can’t wait till older or Harlow if you were any older” cause he thinks once she’s 3 or 4 he can yell at her harder. Yesterday she was whining in the car he screams at her , I then ask him to watch his mouth with the F word” he said “ I can’t she’s making me physically sick” I said so our 2 year old has more control than you ?

Today once he left for work she was fine, I had no issues with her being upset or anything. I am the calm parent the one who gets down on her level and asks her what’s wrong I raise my voice if needed but I certainly don’t yell at her for expressing her big feels I am torn. After this morning when he screamed at her and I stepped in to stand up for her. I know I should have said this but I said “ she would be better off without you” and he flew off the deep end over it. His ex baby mama apparently said the same thing to him but actually left. This is my biological child, she is our daughter together, it’s his biological child as well. he does have a child from a past relationship that he doesn’t see
