((Buttercup)) - from what you've written I'm assuming you were sharing some negative feelings and her response was to send you a pic with the middle finger up...is that correct? If it is, then she's the one who deserves this label in addition to being a mean person. She doesn't deserve to have you as a friend if she can't communicate without being so rude. You're not stupid. I'm sorry this happened and I understand why you're hurt.
