"I thought we're best friends?"

And this person goes, "I just want to make it clear with you so that you will understand. My family knows this, my cousins know this. My best friend is ______. "
You already put me in my place with your words. You made me feel so small. You made me feel so stupid.
Remember, YOU told me we can be best friends and that was just 2 or 3 years ago. I guess I misunderstood the word "can."
