deadnaming :/

ok ok two of my friends irl keep like deadnaming me on purpose (?) Like ive told them i go by he/they and my new name is Ace, but like its either theyre ignoring me or they just dont listen. Even my past homophobic friend didnt care when i told them abt it, they didnt exactly support me but they used my new name and pronouns respectively. Why is it so hard for someone that i constantly tell to stop calling me 'ms. girl' or 'GIRL'. It makes me so mad & i just want to scream at them or punch them into a wall or something and i feel like a physcopath. I do like them as my friends, i really do, but CONSTANTLY they deadname me and i feel so betrayed or hurt. I literally wear trans bracelets everyday with my pronouns & name on them and they acknowledge that. And i feel so stupid correcting them and them saying "whatever yeah yeah i get it ACE -_-" Theyve also said "yeah she says she goes by he/they but like ehh" I just feel so angry and i really want to drop them as my friends but i literally just cant, we have so much history together and i just feel like i would be nothing w/o them. Both of em are str8 so they just dont understand me and i feel like absolute garbage when they dead pronoun me :(
