JV--you really want to even hang around with a girl like this--????
What am I missing here?
I understand the amusement factor--don't get me wrong, I've thoroughly enjoyed reading your analysis, your response and your updates--but now I am amazed you aren't blocking her number and telling her to lose your's. There's a very good reason for doing so.
That list you had for her (another ultimatum, and we've seen how well the first one worked...) may be what she needs. That's a lot, and I doubt she can pull herself or her life together. Look at how she's acting--you think she can do it? I don't care if she says she can do it and agrees, like a whipped puppy, to everything you demand, I doubt she can hold it together for 3 days.
Reason #1: don't waste your time.
Reason #2: Birds of a feather flock together.
This is fundamental. You already can see how immature and psychotic she is, and--who'd a thunk it??--her friends are the same way!
And now here's you. Sticking around. Getting involved. Making ultimatums. Playing games (very amusing, yes...)
Actually, you're already on her level to a certain extent. Ever hear someone say "I just want a nice guy/girl with no drama, but I always get the psychos and the losers and those with drama and..." etc. Even when they seem to find someone who is different and better, they soon find this person turns out to need meds, have drama, etc., and they can't figure out why IT HAPPENED AGAIN.
Why? Because this person responds to and finds attractive those loser/psycho qualities and can't help responding to and attracting it to them. If a decent person comes along, they simply wouldn't find such a person attractive or respond to them AT ALL.
Birds of a feather flock together. Or, "you are known by the company you keep."
How does that apply here? You've attracted her in the first place (she wouldn't have found you worth her while if you weren't on her level) and you are considering getting her under control and keeping her.
You're on her level, or very nearly so. If you weren't, you wouldn't have been attractive to her. And you would be so far gone at the first sight of her psycho behaviour or would've picked up on the 3 dozen other clues of her low-quality/loser traits long before her psycho behavior manifested itself.
Ditch her pronto.
