does anyone have a friend like this?

So I’ve been friends with this girl for like 5+ years. I have always felt like I could trust her with my life and we have always gone to each other for everything, but lately not so much.

She’s been with this really shitty guy for almost a year now. This guy is the definition of TERRIBLE. He breaks up with her all the time and then goes to hang out with other girls, and then goes back to her the next day. He does hard drugs and got her involved with hard drugs, as well. He cheated on his ex countless times (who, might I add, is still in the picture,) he’s cocky as fuck, he’s extremely disrespectful towards her friends (including me) and he’s just an asshole. He randomly texted me one time off of her phone and threatened to beat my ass FOR NO REASON.

Whenever I try to go to my friend for something, especially relationship issues, I get the “awww I’m sorry..” and then she goes on and brags about how “perfect” her boyfriend is, how “perfect” her relationship is, how sexy her boyfriend is, how big his “downstairs” is, etc. like every time I fight with my boyfriend, she just brags about how great her boyfriend is and it drives me crazy. It’s not just towards me, either! It’s all she posts about all over social media

In reality, they break up and fight all the time, I’m like 99% sure he has cheated on her too! I can’t take it, I feel like she’s just trying to make me feel worse. For example, today I showed her my boyfriend’s new tattoo, which I don’t particularly like, and then she AND her boyfriend make fun of the tattoo and my boyfriend and then she goes on bragging about how “sexy” her boyfriend’s tattoos are.

It’s getting to the point where I don’t even want to talk to her or be friends with her anymore. She drives me crazyyyyy and I’ve tried dropping her as a friend countless times and she blows up my phone and my boyfriend’s until I talk to her again. Someone please help me, how do I get rid of her!!
