Ok her behavior is blantantly trying to "be good until I get what I want again." I'd bet my month's paycheck that if you started paying for things again...she'd revert back so fast it'd make your head spin.
I'm glad you are not buying her guilt trips, but the fact that she's still throwing those out there and giving you what you want sexually is EXACTLY why I can tell you this is a manipulation tactic to get back in good graces....this is not an integral change in behavior.
