there’s no coming back from this

i’m joining a new sixth form in a week and as i didn’t know anyone i got to know a few boys. got really into one of them but then his friend was texting me and getting into him too. told the first i was talking to the second and obviously he was really upset and we stopped talking. was talking to the second and we became very close like almost dating them i started talking to a third. i got off with the third but asked the second to ask me out the same day, obviously when the second found out he was not happy and stopped talking but at the same time i started talking to my ex, we started talking and i went kn holiday with him while everyone else was at a festival. they told the third that i was going to fuck him over but he was having none of saying i wouldn’t do that. on the trip i fucked my ex and he put us on instagram where the first boy found it and told the third. i am dating the ex now. i have feelings for all of them and i really didn’t wanna fuck any of them over really i didn’t but now the entire new school hates me and i’ve really messed this up big time
