my 2 best friends are dating each other and i don't know what to do

that's my first blog AND english is not my main language but i NEED TO TALK ABOUT THIS. there's these 2 friends of mine that are dating and i am about to go insane, literally. i love them so much like they're honestly good people and i dont know what i'd do without them but jesus christ can we hang out ONCE without you guys putting your tongues in each other's mouth? hanging out w then isnt that fun anymore, and as an aroace (aromantic + asexual) it only gets worse and more uncomfortable. i already talked to them, but i don't wanna feel like a burden or whatever 'cause like, they're a couple, of course they're gonna do couple stuff. i guess i just dont understand this love thing, i feel so outta place sometimes. 

not only that but one of them has been my bestfriend for almost 6 years now, so we're very close like SOULMATES and now that they're dating i just feel like we're not that close anymore :(i know i'm probably overthinking and being my jealous self again but i cant help but think he's gonna stop talking to me so he can be 100% with his boyfriend and it KILLS me. i try to convince myself i'm wrong and that i don't need to push him away so i don't get hurt but it's so hard. o don't wanna hang out anymore because not only i feel like i dont belong in there but also because i keep having those thoughts of abandonment. i dont know, maybe they're better off without me. or maybe i'm thinking too much??? i'm losing it.
