I've had my trust really battered before. I've removed a lot of people out of my life who were toxic and just overall bad people. I just keep a small amount of friends at the moment.
Yeah, my one friend made up lies about this guy I liked so that I wouldn't want to get with him. Once I decided not to pursue him, my friend started dating him! I was so mad. But I keyed my friend's car and set ha textbooks on fire in our high school parking lot, so I ain't mad
Most of the time, if a friend does something to me or whatever that I disagree with, it doesn't tend to faze me, we have an argument, but we're OK again in like an hour and it's completely forgotten about, but there was one particular time in April 2012 which I couldn't, and will never, forgive and forget, and that was by my oldest friend; we knew each other since we were like 4. It was one of those absolute definitive 'this friendship/relationship/whatever can never be the same again' moments.
That's the reason why I now live by the motto: 'Trust no one'.
I know that sounds pessimistic, but, in my experience, you really can't trust someone fully. Even the ones who you think have got your back for life and would never betray you could betray you.
