so um my bf and i have been dating for about 7 months and we’ve slept together and what not and i’m a sophomore in HS and he’s a junior in HS so just one year age gap. anyway we went to this party a few weeks ago and then he got sick so he went home but we had both forgotten that i had planned to spend the night at his house since my house was empty cuz my parents were home so i didn’t figure to get a ride home with him and when i remembered i just figured that i would go home with a friend or something, anyway didn’t find any of my friends cuz it was too late or they were with their bf already so i went up to my bf’s friends to see if they could give me a ride home and his friend(i’ll call him Z) said that he could take me home and out of his friends Z and me were the closest as he was my bf best friend so we all hung out a lot. so Z said that it was fine to crash at his place so we left and i took a bottle of vodka(cuz why not lol) and we went to his place, so long story short ig we kept on drinking and got pretty playful cuz we got pretty drunk and one thing lead to another and we were having sex and we never noticed till we woke up the next morning. so um now i’m completely screwed cuz i want to tell my bf but i can’t just go up to him and tell him i slept with this best friend and now Z says that i can leave my bf to start a new relationship and i’m literally stuck in the middle and can’t find a way out cuz i messed up bad and i hate it so much
