Wow, she played you and then asked you not to talk to her again? If that went down as I'm picturing it in my head, she just went down several notches in my book, not that she was very high to begin with. I tend to have pretty good character judgment skills and I have always gotten a very bad "vibe" so to speak from her. I know a manipulator when I see one. That said, I would never say anything to you about such matters, because those are lessons I think you just have to learn yourself.
I can not believe that Bill has the audacity to pretend like he didn't know this was coming, or that Ivy wasn't the instigator in this situation.
Nick, I think you are awesome, and Ivy is way way way too trashy and low for you. If I wasn't taken, I'd hit it. Seriously!
