former best friend

Often, best friends can be the most important people in your life. They are the person you can call if you need someone to talk to at 2 AM; the ones that will keep your secrets, support even your most convoluted aspirations, and help you with whatever you need, even if they think it's crazy.

However, not all friendships, even those with your best friends, last forever.

Sometimes, friendships end naturally, as the two people grow apart. Other times, the friendship ends because one party did something malicious or made an irreparable mistake.

Redditors have plenty of stories of those kinds of friendship enders, and are ready to share.
