Is AUTHOR wrong in the post ? POST : As the title explains I told my best friend's ex she was toxic .

So me and this girl have been friends for like 7 years. And she's been a toxic manipulative person for the last 3 years I have dealt with it for that long. And why is she toxic lemme tell you. She Is a complete dick to me  when talking to her friends, she bad-mouths me to her friends and family, she gets on my back about eating my own food by telling me "I need to learn how to ration my food" which wouldn't be that bad if she wasn't eating my food and living in my mom's house, and she keeps talking about things I do bad weeks after it happens. So lemme get back into the story.
She was being a complete dick to me by yelling at me for eating my food . And I left to go to my room. I was kinda mad so I acted out of anger by texting her ex who she still loved what she has done to me. And guess what her ex told me that she had told her and her friends that I'm a dick to her and that I'm toxic af. 
The reason she stated:
1: I Snore keeping her up at night
2:I Eat her food 
3:I am "racist" towards her
So I can't speak on her side but here's what I realized I do sometimes 
1:I Do Snore but I can't help it
2:I ate your food 1-3 times plus you're living off my dad's food 
3:yes I do make racist jokes but you have to say when they make you uncomfortable I understand it's not ok to make racist jokes but she calls me a beaner! 
Later that month She figured out that I told her ex about her toxicity. And she called me a "Fucking dick" and "toxic friend". She started crying and telling me that I shouldn't have done that and she hasn't let me down about it. Now her friends hate me even more and I'm still stuck in a house with her
