Is this a kind of conflict? ?
about a year ago one of my friends lied to me about very personal things so, when i had discovered that she was lying to me it felt like my heart had shattered, i trusted her dearly and i felt as if i couldn't trust her anymore i told her i couldn't be friends with a liar. she threw a rock at me and yelled at me saying i was a bad friend to jump to conclusions and i didn't deserve to be friends with her i then told her that she didn't deserve to be friends with me.

You see, in my opinion, jumping to conclusions when you don't know about anything can end on very bad terms...like very bad terms. Based on what you wrote, "She threw a rock at me and yelled at me saying I was a bad friend to jump to conclusions and I didn't deserve to be friends with her.", that is an example of jumping to conclusions too fast. How does she know you jump to conclusions too fast?  How can she predict when she doesn't know. But the fact that you knew she was lying about personal things and trusted her a lot with what I learned, clearly proves that there is some sort of miscommunication and that there might be a conflict if it doesn't get sorted out. In your perspective, even in mine, I wouldn't want to be friends with someone who lies, so I understand where you're coming from. This is my opinion, but if it doesn't get sorted out, it could possibly lead to bigger conflicts if not fixed now.

Hope you don't take it to heart, just expressing my thoughts!
