told a friend her toxicity was getting to me

we were friends for a few years, online only but gamed and voice chat almost daily. i never shared with her how i felt until it became too much for me to tolerate. she is often judging others and speaking badly about people. to be fair to her i would sometimes join in or be complacent so she probably thought it was ok. i let it go on a while.

finally i told her how i felt. she said she understood and wanted to talk about it. i wasn't sure what to say so then i told her i need space to think. honestly, i don't really want to be her friend anymore.

the space made her not feel well so she blocked me. i guess it was a lot at once. then i emailed her to tell her i've been struggling with what to say next thats why i needed space to think.

she pretty much blasted me, blamed me, and nitpicked all the things i told her were bothering me. it was very overwhelming and gave me heart palpitations.

i apologized multiple times for hurting her, now she wants to figure out a way further but i'm not sure that i want to.

thoughts?
