PLEASE HELP ME!

I’m sorry if this is long but I need help! I have no one else to talk to about this

So I’ve been with my boyfriend for 2 years and he is friends with this one girl and she used to bully me a lot. I would literally cry myself to sleep. She would tell me how ugly I was and so many awful things you wouldn’t be able to imagine. And then she’s being 2 faced so she was pretending to be nice to because I was dating her friend and now she’s so mean to me again. She sent me very rude text messages. I can’t tell you guys how hurt I am.

She’s started out saying that she thinks I’m using my boyfriend but I’m not, I’m in love with my boyfriend

And my boyfriend knows she’s bullying me but isn’t doing anything. Idk what to do

I love him but I can’t deal with this
