Why do a friend go behind your back to talk to your crush?

Anonymous
I’m not sure how to confront my “friend” about this, but I’m already distancing myself from her and her sneaky ways. I’ve found out that she tried to sabotage my chances with not one, but two of my crushes when I started talking to them by going behind my back and trying to speak to them too even though she already has a boyfriend. Why would someone do that and should I confront her or just cut her off
