Geneva Ayala is upset about some of the Internet reaction to her ex-boyfriend's murder ... particularly people who assume she'd dance on XXX's grave. She said, "i didn't lose my life. he did. it's permanent. i'm still here. like how do you think that makes me feel?"

Geneva also called it "disgusting" that anyone would attempt to speak for her.

As we reported, XXX was awaiting trial for the alleged abuse of Geneva, and also for multiple counts of witness tampering in the case. Prosecutors think he coerced Geneva into not testifying against him.
