i do not know

is it disrespectful when you talk in another language in from of your SO? he got mad at me when I was talking on the phone with my cousin. but it came naturally, I didn't mean to disrespect him but I didn't tell him that. he was talking and talking and telling me to say sorry. EDITED: So I talked to him whatever you girls told me on the comments and I think he understood because I asked if he still thinks it was disrespectful after I told him what it was and he said of its like that ok.
