hey guys, semi vent but need tips

hi everyone! i hope you are all well, im just gonna quickly talk about what’s going on in my life atm! so recently as i’ve posted about before ive recently had an overdose, and since then ive started new medication for adhd, anyways thats besides the point (even though im ecstatic about it!), ive been friends with these two guys in my friend group for like a year and a bit now im going to use nicknames for them, for the first one im going to call him boy A and the second one is boy B, mme and boy A had a bit of a tense part being friends because he got with my best friend who was also in the friend group, ill call her girl A, so its me girl A, boy A and boy B in this group and all goes great. me and boy B have always been close friends and i see him as a really good friend of mine and ill always be happy for him no matter what, and anyway on my 16th birthday i got drunk and we had our first kiss, i wanted it to be with someone i trusted and im happy it was with him but i dont feel romantic towards him and we both know it and have talked about it, anyway roll around the next week its my friends birthday party, also her 16th and boy B gets insanely drunk and starts crying/venting/throwing up, and then he starts confessing his feelings towards me and saying how im as great person and such so im comforting him making sure hes drinking water ect until he gets picked up, and ever since then we just haven’t been friends properly, i’ve been talking to a guy who he absolutely hates and makes fun of constantly even though the only time they’ve met is in a group chat a couple of times, me and girl A who are best friends hang out without both of them anyway and even though her and boy A are dating he doesn’t really hang out with just us two anymore and their relationship has been kinda rocky, boy A and B have been going through kinda a rough patch recently and i want to help but neither of them are mature or sensible enough to accept it and i dont know what to do, i dont know if boy B doesn’t want my help cuz hes embarrassed that hes already vented to me in a drunken state or if its about the kiss, which i doubt because hes speaking to a new girl now anyway, but it really difficult to get through to them cuz they never wanna talk or hang out anymore which is a real shame cuz they were basically my only friends, anyway i dont know what to do but u hope none of them are mad at me
