Is this a normal behavior?

My partner wanted to test the temp of the water he boiled, only thing we had was the armpit thermometer, and the one where we place it against our forehead to check our temp.

I gave him the one where we placed it under our armpit, and he asked me how to use it. I told him how to use it, and he did what was told. The thermometer read "H," meaning "high." I said that maybe its too hot, thats why it only says H, which means high. He got all angry, and yelled at me that im so stupid. He told me im delusional, im a liar, stupid, have no brain, and i dont ever want to admit that idk how to use it. I told him i do know how to use it, i already gave him the instructions, and told him why it only says the letter H. He refuses to accept my answer, and told me to just tell the truth that idk how to use it, thats why i used the word, "maybe." Yelling at me loudly constantly, telling me i have issues, and calling me names constantly.

I was at shock at how hes so mad over something that isnt even necessary to be mad about. Like he has serious issues, and it really made me look and feel about him so different now. Like the love i had for him is, lost.
