Me and my friend fancy the same guy?!

If I were in your shoes, I would talk to my friend and make an agreement that neither of us would pursue them. It's always better to put a solid friendship before a prospective relationship.

I really like him though and he likes me! Literally I have liked this guy more than anyone before so it kind of feels like a waste to not even try but at the same time i get that she would be superrrr annoyed

Seriously, talk to her about it. Whatever you do, don't go behind her back unless you don't intend to keep her as a friend.

Is it worth potentionally losing your friend over?

I cant say that for definite but it might be

if you consider her a friend, you won’t put some guy you barely know over your friendship. seriously, a lot of guys are just massive d*cks, and you won’t know if he is or not until it’s too late and you’ve already ruined your friendship with this girl. whatever you do, DO NOT go behind her back. just talk to her first - she might not actually be annoyed! if you explain that he likes you back, she might realise she probably doesn’t have a chance with him right now, and she may even support you!! however i’d be absolutely certain you want to pursue a relationship with this guy before doing so, because a silly fling or infatuation is not worth losing a close friend over.
