My boyfriend said that I can only wear a bikini when I'm with him?

I told my boyfriend that I might be going to Thailand with my parents, and asked his opinion on certain swimsuits I should buy. He said that I cannot buy either of them because my breasts would "fall out" of them and that because I have an hourglass figure, I cannot wear it. He then said that he cannot give me "permission", to which I replied that I don't need anybody's permission if my parents are fine with it. He then told me not to disrespect him and that some things need to be approved by the partner. Did I really disrespect him?
