Should i still be besties wit her?

Mi bestest friend ever is awesome! Sometimes... She and i have been besties since tha start of '09. I can trust her with pretty much anything, and she tries too be there for meh as best she can. We are very different chikks. She likes too whore around with multiple guys who, in the end, mean nothing too her. She sayz she's "in love" with every one of them. I have seen hur get hurt because of this (emotionally) but she keeps duing the same thing every time! i alwayz ask her too olease stop being such a hoe with all these guys (yeah, we're really honest wit eachother.). She promises too stop but she never does. Alot of my other friends don't like her, and they keep telling me to stop hanging out wit her because she might turn meh into a hoe. I ignore these ppl, but sometimes i'll just be thinking and... my friend pisses meh off alot nd we get in (small) fights, but we alwayz make upp... She's hurt alot of guys that are also close friends. Mi friend jorge thout they had something nice going, but she was dating armando at the time. (She and armando have been dating for a long time and they alwayz get into fights, so it's hard too tell when she's cheating on him. She lies too meh about the guys she dates (denies flings) and the only thing i can du is lusten too the other friends ***** about her.) while tha situation with jorge and admando was going on, she had also been flirting wit her ex (and also mine) cesar. Cesar said she broke his heart and that he hated her, but when he's around her, it's almost like they go out again. It doesn't bother me that they're close again, it bothers me that he wrote her a note tha day he broke up wit meh saying SHE was ALL he could thinkk about. (did he use me too get xlise too her again!?) so i would like too kno if i should still be friends wit this slut that happens too be mi bestie?
