Boyfriend calling me and son attention whores

not even 30 minutes ago, my son (17 months) and my boyfriend were in the kitchen. my son fake coughed to get our attention and my boyfriend blows up calling my son an attention whore!!🤯😱 that really pissed me off so I told him he better not call my son one of those again, he just wanted us to look at him and then my boyfriend has the nerve to call me one too!! he responded with “youre an attention whore”😱 I feel extremely disrespected. for him to call me that for no reason and ESPECIALLY for him to call OUR OWN SON one just because he fake coughed! I got in the shower and he was in the living room then decides to invite himself in the shower with me, trying to act like he didn’t just disrespect the hell outta me for no reason! I told him to get out and that nobody invited him in there with me. and that he didn’t even apologize to me or our kid. he thinks that calling us an attention whore is totally okay, when it’s not! what do you all think? would you feel disrespected? would you have gotten upset?
