I can see alot more going on than just a disrespect when a woman says things like that.
It seems to me like a warning of things to come, it sound like she is giving him an excuse for the break up thats gonna happen soon.
Not necessarily. She was looking to get dumped like her ex dumped her to re-ignite those feelings of abandonment and lust. If not from OP, then from someone else.
Something clued her in that OP was not so willing to walk away so she advanced that statement (although true), a shlt text of sorts, as the final test (meaning there were other failed tests that led to this).
But OP stuck around.
Understand, a girl would not advance such a statement unless she knew she could. If she never knew where she stood with OP, she would fall in line and not likely jeopardized the relation.
Her lost interest is due in part to her KNOWing her status with him rather than guessing and second-guessing. Nothing bores a person more than something or someone whom has been (emotionally) conquered.
