Are Scorpios normally this underhanded and sneaky?

For the past several months my boyfriend has been reconnecting with old high school friends through facebook. One friend particular had been has female friend. However, they briefly dated in their late teens, but continued to stay friends. They hadn't seen each other in 10 years. Anyway, she had a small get together at her house yesterday and invited us. So we decided to go. So when we went to her she was NOT hospitable at all. Didn't offer us anything. Her house looked like hurricane katrina hit it. Anyway, she did a couple of things that were very inappropriate. First off, when my boyfriend went outside to smoke she started to show me pictures of her fiance in her cell phone. At first I was cool with that until she started showing me nude pictures of him. Then she told my boyfriend she wanted to show him some pictures of her and family on her phone. I was sitting right across from them so I wasn't really paying attention to them. When we finally left and got into the car my boyfriend told me that she showed him nude pictures of her. I thought he was lying,but he stuck to his story. How could somebody be that bold. The ***** even gave me hug when I left. I'm on a virgo/libra cusp and my boyfriend is a cancer.
