AITA for double checking someone preffered name
So Last year i went to this party, and there was someone who had identified as transgender. Upon this party, i had heard people refer to them as their deadname and chosen name. Some said they went back to their deadname, some didnt. Me being me I had gone up to this person and asked “im not sure if this is transphobic to ask but are you (deadname) now or are you (chosen name), im so sorry if it is” anyways he tells me im not allowed to ask someone that and i apologise and said i wasnt sure if it was thanks for telling me and i walked away- upon returning to school i was approached by friends who had told me he was going around calling me transphobic. When i tried reaching out to apologise again, he had blocked me. I was dating someone in their friend group at the time, who assured me he wasnt saying anything about me- flash forward 4 months later. I was invite to a party and they didnt want me there because i was really transphobic to them and didnt apologise (WHEN i did) and i was spreading lies about them. Which extremely confused me as i never brung it up” Nobody but my boyfriend, i had told what happened because i felt bad and was unsure what to do. Leading to an arguement between me and them: they said stuff you told everyone thats why everyone knows and i assured them i only told my bf and they responded with “the only people i told were the people at the party” and “if my friends asked me that then its not transphobic but we ARE not friends so it is” This launched into a breakup with me and said bf. Any flash forward; i have later found out they have been telling people, i meant it with intent and i knew what i was doing. And has told my own friend a different “truth” to what i got told furing the arguement: saying i had meant it to hurt them when that is further from the truth and further more numerous people have told me they have been told countless stories by the person who “wanted” it dropping.
AITA?
