Is this normal that this happens to me?

Okay... SO I added this girl on Facebook, which I thought that she was really sexy and then we chatted for a little bit and then she asked if she could come see me.... I said yeah, sure and she asked me to send her money from Walmart. I told her that I don't know how to send her money to WalMart, I told one of my buddies on Xbox about it and then said it was a catfish. I agree now because the pictures didn't look all the same. It sends a big flag that someone would want me to pay for their ticket to come over and see me. Usually girls will pay for it themselves. She sent me a naked picture of her since she didn't like that I said that I sent her money when I didn't, she also sent me a text on Facebook saying that this was what I was missing out. She told me that her brother was pissed off at her and he was cussing her out, so... I asked before that why her brothers last name was different from hers and she said that he hated her dads name so he took his moms Maiden name. She also said that I sound like I am 16 years old because I talked to her about sex and her boobs. But its really stupid that she would act hypocritical about that when the way that she represents herself is very revealing. She finally blocked me after a few days. What do you is it normal members think about this?
