should i keep talking to someone after finding out about their disturbing secret nsfw twt acc?

so i (20f) have been talking to this girl (19f) for about 9 months. we’re not dating, just close friends, and we talk & sleep otp daily. recently, i found an active nsfw twitter account of hers. the account has some seriously disturbing stuff on it, like non-consensual themes, violent kinks, and agep!ay. i didn’t even know this side of her and honestly, it really shook me..

what’s also confusing is that she always said she’s a femdom in the way she talks to me, but on this account, she’s really submissive, into ageplay, and talks about some pretty unsettling things.

and also she always says stuff like “oh people who have non-consensual themes, violent kinks, agep!ay r4pe !nc3st and all are so weird to me they disgust me .”

i didn’t tell her i found the account, but i msged her saying i felt sick and had this pit in my stomach after seeing something disturbing. she immediately responded even called me, kinda asking if i saw something violent or non-consensual. it made me feel like she was trying to gauge what i knew, like she was kinda confirming something.

the next day, she apologized for being harsh the night before, but it felt kinda shallow, like she wasn’t fully understanding why i was upset. i didn’t bring up the account, but i’m seriously struggling. i don’t know how to even bring it up, and i’m just really disturbed by what i found. at the same time, i don’t wanna cut ties just because of this, especially since i care about her, but idk how to move forward now.

what should i do? should i just walk away but i genuinely like her. i stalked the acc idk if shes into these things bc of trauma or what
