Am i screwed? yes or yes

ok so this is kinda long so this is the VERY short version if you don’t want to read:

me and my two friends have a little three man going on and the guy i’m "talking with" likes me and i don’t like him. my friends want me to stick with him even though i don’t want to so i feel like i’m lowk leading him on.

Long version:

Since last year my one friend - fake name L has liked this one guy and my other friend - Mao has thought this other guy was cute so this is like the backstory. So this year when L actually managed to bag the guy she liked - red, the guy Mao thought was cute - Green was like "Imma get with Mao for fun" like in the beginning it was all a joke. So i was like yo what if i get wit one other their friends for fun too and it can be like a little joke threeman while L and red actually talk to eachother. So i got with this guy Sus and before this we have never even talked to eachother. He even said himself to someone that he'll like me as a joke or something idk BUT NOW. he likes me for real. this has been going on since september. and trust me i barely text him, i don't cuddle with him or do weird stuff, i just talk to him and genuinely i don’t say anything that would lead him on. My friends want to make this last till february of NEXT YEAR. And btw Green and Mao are actually locked in. Even though Green originally said that it was all a joke, they're the most locked in out of everyone. It's insane. But L n Mao don’t want me to end it because they're like "when r we gonna ever find a threeman like this ever again" and it's true like you never see a threeman.
Anyways, what do i do. Like i need to end this but my friends r gonna kill me. N Green keeps interrogating Mao about whether i like him or not but she says idk. Also me and Sus aren't even talking. Like we've never confirmed it and Green also asked Mao when Sus should ask me if we r talking and i’m actually gonna say no.
So what do i do and if i do end it with him what do i say and what do i tell my friends im actually fucked.
