Becuase she is confused and confusing... she is a good woman:)
You don't know what's going on becuase she doesn't either. She may **think** she likes you (bare with me here) but this will change when she turns that page in her drama life:) Let me ask YOU a question... if she was really into you and worth your time, why would she be playing these games with you? She is still talking to you after however long becuase maybe she is bored... she sounds like an attention whore as you say, and maybe she needs someone (aka you) to occupy her time with or maybe a little underling to chew on before she goes for her next big kill... ok Im being a bit presumptuous here:) But really, maybe she just is bored and wants to say hi... just don't forget all the shit she has put you through... and YOU should occupy yourself with pining over a girl that may actually reciprocate! I still say she's no good...
