Gentlemen, as a female I'm here to tell you that if she recently broke up with someone and she's calling you, its not because she never quit thinking about you. It's because she's desperately trying to find a back up guy. She wasn't into you then. She isn't into you now. But you were into her once and she's panicking that she's suddenly alone. So she reached you in her mental black book of guys who were once into her and might serve her need for ego-stroking for the time being.

Go bang her if you want. Just keep your self-respect and remember where she's coming from.
