seeking guidance: should i stay or should i go?

hi, i'm (F28) new here and grateful i found this community at this moment. my best friend (F30) of the last 5 years has BPD, we've never discussed it but it's textbook. since very early on in our relationship she has had outbursts at me calling me and my actions "mean", saying that i'm "punishing" her, and that i intentionally try to hurt her.

my anxiety used to catapult me into fixing issues that weren’t mine fix. last year i started taking SSRIs and now with my anxiety more under control, i've been pushing back during her outbursts.

i'm preparing to move to a new city in 2 months and she has been ignoring my requests to hang out or talk on the phone and has ignored my feelings when i said i missed her and was feeling lonely.

we got into a huge fight the other day and she said many hurtful things to me, accusing me of ruining our friendship. i asked for a week of no contact to process everything and am now coming to terms with the abuse i have received and enabled for the last five years.

i am struggling right now and am strongly considering ending our friendship. i am seeking advice on how to approach that conversation or really any future conversation i might have with her.
