My best friends gf might ruin the thing i got going?

[Phillip]

alright pay attention closley i know this girl who ive really come to like recently. i asked and she wanted to be with me but wants to wait until next year when we are in highschool. i can wait. but a few weeks ago she accidently put up a pic of her lower body in just her underwear up on facebook on accident and my friend commented "blush" and she said not to say anything and that it was for tumblr. i already knew about it but my friend told me anyways and i asked him if it was ok to tell her that he told me because i was curious and he said no. then i was telling his gf about it and said i am a "sexsist asshole" and said she was going to tell the girl i love after finding out about her name she went to her profile after my friend retardedly gave her her name. and she started saying "shame on you for liking her shes ugly and a whore." which i assure you she is not a whore and i dont think shes ugly, she is an amazing person. then my friends gf said she will 'talk to her about this' and i said "um no you wont." and she said " i have every right"
what does she think is going on she clearly is assuming and not paying attention. my friend said he will make sure it wont happen.
what do i do?
