what do you do when your bests friend is having a relationship with a guy

[Meilsie]

who has a girlfirend? her name is Cat and his name is Chris and his girlfriends name is Des. Chris and Des are in love. BUT Chris and Cat are in "love" too. he told Cat that she only has to wait until the summer and they can take their relationship public because he is going to take a "break" with Des. but Cat does not understand that "taking a break" means that they will get back together again. they make-out all the time and i am the secret keeper. i cant get it in Cats head that she is #2 and Des is #1. But...last week Des found out what was going on. and Chris pinned it on Cat. So they didnt talk until today. they have been ignoring each other until now. they are starting to make up and i dont know how to stop it. she is getting back into the hole....PLEASE HELP ME SAVE HER FROM MAKING ONE OF THE BIGGEST MISTAKES OF HER TEENAGE LIFE!!!
im desperate, i dont want to see my best friend crash and burn.

tell her to not get to involved becasue she will look like the bad one in the end becasue he'll leave her alone go back with his girlfriend and people will start calling her a hoe, so tell her its just best to leave him alone
