From everything that you've written about how she's treated you and her bizarre actions calling your employer for an internship, my alarm bells are going off. She's just using you, sorry to say. She's 46 and there's no excuse for treating you as she has. Maybe if she were 12. But she's middle aged.

She clearly wants you to be her ego booster until she gets what she wants from you. She sounds like an emotional vampire aka a narcissist. Avoid her like the plague if you can. She doesn't seem like a genuine friend at all.
