school ball

alrigth so i need some other people opinions on this i had a school ball last week and this girl georgia has been with her boyfried for quite a while but the thing is durring the ball she was ALL OVER siad boyfriends best friend and me and my whole friend group saw it but i dont think that the boyfriend knows bc today in school they were still toghther and the boyfriend and bestfriend were stilll talikng like normal , and the thing is when i mentioned the amount of couples making out at the ball she clearly got shocked like eyes about to pop out of her head and idk if i should ask her about it i mean ive known her for a fews years or should i say smt to the boyfried bc its really awkward see them together i feel bad for the boyfriend bc if he does find out he will both his bff and his gf so i just idk what to do bc literarly no one but my friend group saw bc they were making out at out table while we were gone but also im not very popular so i dont want to start anything between them or have peole hate me over trying to break them up 

so like what should i do
