What's diffence between anger/hatred and indifference? Is it bad if ex upset

Just wondering I just recently had a phone convo we would joke or talk normal but than anything Brought about about me she reacted mad,upset,or angry why is that? It’s like she hate me but I didn’t do anything to be hated and she now saying she don’t want a relationship ever she hates everyone and she wanna be alone forever lol

Need advice asap

What do you want advice on? She sounds like she is being really immature. I would establish no contact.

I did that and only established contact 3-4 times in two weeks. I can establish it again ? And does that sound like anger or indufference( pretty much I’m trying to see if she still care)
