Girl drama

Well in my freshman yr I had problems with a girl.
And she wanted to fight me and but I didn’t want to fight her because im not the fighting type of girl you know .
But im a sophomore and I thought she was going to drop it and I never see her around but...

I was around my boyfriends class and then um she was there.
And she kept looking at me and I heard her say to her friend that “oh you want me to tell her something”.
And so I told my boyfriend ima got to class.
So then 2nd period I saw my boyfriend and he told me oh you saw that girl by us and I was like yea why.
And he said that she started talking sh*t to him about me and stuff so then he said.
Oh she doesn’t want to leave you alone and I was like yea since last yr.
And he said he was going to get a girl on her.
And beat her a** and make her bleed.
But I don’t know like I feel bad.
Why cant she just drop it you know.
Does she hate me this much,.
What should I do to make her drop it

just ignore her
be the bigger person
pretend like what shes doing doesnt bother you
and just go on with your life
