From the way she is wearing oversized clothing I would say she has body image issues and no doubt is quite vulnerable. The way she wears that makeup is like she is trying to hang on to her youth, and sleeping with a 14 year old boy is no doubt a manifestation of it. She wears that ring on her middle finger to tell the world she is single and ready to mingle. I would also say she has been in quite a fair few abusive relationships, which ultimately have messed with her head.
Like I always say - women are becoming increasingly BAD at selecting relationships, even worse than 10 years ago. Women even agree with this statement.
