AITA for “choosing my boyfriend over my “friend”

english isn’t my first language so if there’s any spelling or grammar mistakes i’m sorry 😭

my “friend” and i were friends for 7 years my boyfriend and i have been together for 7 months (6 months when this happened)

and idk if this matters but my “friend” is 18 now.

hear me out, I (18F) cut my friend (17F) off when she made me chose between her or my boyfriend (18M) it was a long story, but all that needs to be said is that she accused my boyfriends friends of sending her something stupid, and stating that my boyfriend is “friends with people like that and that my boyfriend too is like that”. when I called to calm her down, she started screaming and saying she doesn’t want to be my friend anymore. my boyfriend spoke to her, assuring that it had nothing to do with him or me and actually tried helping to calm her down. since getting in my relationship she barley said one nice thing about him. after i said i shouldn’t have to chose between her or my boyfriend. she insulted my boyfriend one last time, where i defended him respectfully. (she called him a dumbass and i said, I’m sorry he’s not a dumbass). she told me in doing that i “made my choice”. the next day, she sent me an audio on insta about how she felt betrayed, i tried justifying and she said “you let me go”. later that night and the next 2 days she continued to spam me with insta dm’s about how i was “fake to do that” and that i “never cared about her”. after i ignored it, days later she called me just to scold me for 20 mins straight. that’s when her boyfriend (18M) texted MY number calling me a dumbass and all of this stuff. i sent his number to my boyfriend and my boyfriend told the him to leave me alone. in response, he threaten my boyfriend about getting him jump if something like this “happened to his girlfriend again” and called my boyfriend mentally unwell.

adding this all in. this “friend” tried to sleep with my EX, used me for my money (and admitted) constantly manipulated me, and CHEATED ON HER BOYFRIEND.

also i think it’s worth knowing that this all happened when i quit my job (meaning i was losing a money income) and this “friend” was aware of this, making me think she made something up because she wanted nothing to do with me when i lost my $$.

also on the 20 min phone call she said she was “testing me” to see what I would do, but that makes no sense lmfaooa

i blocked her on everything. i do miss her but i have no plans of reconnecting or talking shit out anytime soon.

am i the asshole?
