Should i forgive her?

So basically i found an online sister last yr on discord, i don’t make a person my sister but she was different, use to listen to me talk to me and more over i use to solve her problems but in july 2024 after like 3-4 months of this relation she blocked me Today she texted me,

“hello bhaiya how are you i am sorry for blocking you, i was forced and i was blackmailed by my boyf, ex boy now. i missed having a bestie all throughout and now i know its not js okay to pretend like i did nothing but i hope you understand.”

I feel like she might be vulnerable that’s why she is texting me, treated me like an option and when i became serious like a big brother she blocked me, What should i do in such a situation?
