Friendship torn apart because of boy drama

I've been best friends with this girl for 2 years now and we ended up liking the same guy. Our class went on a field trip. She knew I liked him and she has a boyfriend, but she started flirting with him and hanging out with him and leaving me and my friends.

So my friend told her I'm mad at her and to stop because they're flirting and it seems like they're going out.

So now she's making my life hell and calling me names...and I can't let her put me down and ruin my day!
