Boyfriend taking another girl to prom

Kate

Well my boyfriend just told me he’s taking another girl to prom cause she pressured him into taking her. Like they are best friends and went together last year, but I’m his girlfriend... And I was really looking forward to going since my school doesn’t have one... what do I do?

UPDATE: he said he was joking 🙄 after a week of me worrying I finally asked him about it. AND HE WAS JOKIN
