Yet again… the arguing commences

For context, my S/O games and cusses. He knows he has a mouth, he is aware that he needs to stop and he knows that I do not appreciate it. I will say that every relationship is different and To each their own! Please no snarky comments about cussing.

He was watching a YouTube video on his phone. I was on my phone next to him, listening to his video. I hear the words “f*cker,” “J*sus Ch*ist,” and a few other small words that I didn’t appreciate. I calmly looked over at him and said “I say this in the nicest way possible but I don’t want to listen to that. It is absolutely disgusting.” He told me he was listening to it because he thought something was funny. I then calmly said, “how can you listen to them talk like that?” I got up to get my shirt so I could leave the room and all he says is “okay Kimberly” with attitude and annoyance. I calmly said “what do you mean?” And he just says “okay Kimberly.” I left the room to get water and contain my feelings. I told my MIL what happened and she was disgusted at him.

Am I wrong for saying what I said? I was very calm about the whole conversation and I felt like he was being disrespectful towards me
