Is she promiscuous...................…

So i ve meet this girl, she has a boyfriend but gave me her number. Last night when i was out i ve seen her with another man and she was all over him, like touching, leaning on him, dancing with him, like she did with me last time we were out. She told me that she was going out with a friend. Well she is like that with all man really. I don t know if she cheats or not. She told me that she got to know her father when she was 12, and that she lives with her mother and her sister. So what do you think, is she an attention junkie, wants to change her boyfriend or is just promiscuous??
