Ok what is this guy doing..straightforward answers please?

this guy used to think I was hot...I saw him tonight and he was rude to me..like gave me the cold shoulder. When we were all hanging out he talked about all the girls he wanted to bang. My friend and his girlfriend suggested that we all watch a movie and he acted like he really didint want to. He recently got out of a relationship. I'm a very beautiful girl..so why am I not on the list of girls he wants to get with, and why is he rude to me.
