Boyfriend is upset that I love my kid?

I have kids and my 14 year old is deaf and has cochlear implants. My boyfriend has made comments in the past about him being tired of TV adding in deaf people and that they're just trying to be woke and stuff ... In front of my deaf child. Which I've spoken to him about. My son was just excited to see a deaf character in a show he likes. My son recently convinced me to watch a show with him that takes place in the same universe as the other show he likes. It basically takes place in Hell. It's called Hazbin Hotel and he's been singing the songs from it. There's this song called more than anything in the Show that Lucifer sings to his daughter Charlie. I sing the songs with him and we are in the kitchen singing while washing dishes and we sang more than anything and I put my head on his head and sang "I'll shelter and adore you more than anything!" And he got mad at me and asked why I would shelter and adore my child over my life long partner. I said we were just singing a song together and he said "Well then why did you put your head on him like that." Like. The song was a song Lucifer sang to his daughter so clearly it's a parent child relationship song. He yelled at me in front of my kids and it was awful. I had a talk with him and I told him I think he has an issue with me loving my kids and if that's the case maybe we shouldn't be together. I tried to tell him as nicely as possible but he's saying he's supposed to come first and I should only be saying things like that about him and tried to sexualize the relationship between me and my children. It was awful and he finally left and has been blowing up my phone. I keep trying to tell him that it's not him but I think he needs to date a women without kids. He's making me feel like an awful person.
