She's shouting down the phone on a voicemail to me, about how unfair I am. How I'm a s friend, I don't deserve her, she's going to speak to her BF to get him to talk my DP round.*
She is delusional.
How does she imagine this is going to work for her?
That her desire to squat in your home is so righteous that all that needs to happen is for her, her b/f, & your partner to harangue you until you cave in ... & then you'll see the error of your ways, & everything will be peachy?
Who could possibly live like that?
It is she who is the shit friend. She knows all about your anxiety, yet feels justified in piling into you like this. Don't feel small & deflated OP - that's what she's after. She genuinely believes that if she makes you feel bad enough, you will give in.
This is the real her. This is what happens when her 'friends' don't take orders. She is a monster, I hope you block her & dump her. No need for you to do anything about that btw - I'm sure when your lovely partner listens to her batshit ravings, he'll contact her/her b/f himself, to tell them to fuck off & stop bullying you.
