So, I've used this key before and I'll use it again

Me - 14(m)

X - my crush from a couple of months ago 14(f)

Y - her friend who is convinced I have a crush on her (I don't) 14(f)

Z - a mutual friend 14(m)

Basically, Y makes any sort of interaction with X downright impossible, and it's already hard because I'm an awkward fuck but if I'm trying to talk to X, Y will butt in and say something like "why don't you love X anymore?!?!??" 100% serious and make both of us feel awkward.

X knows I liked her, she was the first girl I ever asked out in fact, but we get along relatively well and I haven't liked her for several months. She is really nice though and I want to be friends with her. Y is my obstacle.

This all came to a head when one of our mutual friends made a rather sexual joke about Me and Y, it was weird, but they're friends so I don't think it's a big deal. However, she heard her name and pressured me for 25 minutes to tell her, and eventually I gave in. She knew that Z was the one that told the joke, but she called ME disgusting (specifically me btw, I asked if she meant him, and she specified that it was me) so obviously I was peeved, but didn't take it out on her, because I'm practically allergic to beef.

Well, turns out, a week later, she's claiming that she never said anything and I was lying, but she still acknowledged my reaction, so is basically stating that I got angry over quite literally NOTHING.

As soon as she was out of earshot, I said to Z that Y was a gobby bitch (that's British talk for big mouthed) and he called me out for it, saying that it was messed up I was so mean over something so small even though it was his fault, so AITA?
