(HPD)EDIT: She might or might not have HPD, but if she does fit many of the patterns below she does.
This question points to a well known and studied personality disorder, the Histrionic personality disorder.

EDIT ENDUsually but not always these women are attractive, fun, full of life, they like to hook up with guys and they need a fan club as important as possible, the typical deal being the members of the fan club give them the attention they crave in return of sexual favors.
And how do you deal with the inevitable jealousy and insecurities that naturally appear in your life? You can complain about how insecure it makes you feel because you know they want to sleep with her and how she needs to stop it. You tell her how she needs to live her life so you feel better and you can leave her if she doesn’t comply. Spending your life trying to control the people she spends time with (The Outer) is a flawed and painful strategy and is never going to allow you to create an incredible relationship with a high-quality woman.
One thing you’re never told about attracting high-quality women is almost without exception, you’ll find them surrounded by other guys. And they’re going to want to spend time with her, flirt with her, sleep with her, whatever… How do you deal with them texting her, calling her, wanting to spend time with her? Unless you lock her in a cupboard (holy fuck, please don’t), she’s going to meet guys just by living her life, and you can’t control that.
The problem with The Outer strategy is that it only really works on insecure women with no options.
So, that brings us to strategy 2: The Outer strategy dealt with everything outside your control, namely her, her communication, and her friends.
