Hey man I think she's already got you in her game. Making comments like no time cause of her kid and shit. She was waiting for you to say something like " that's crazy the right guy will make time for both of you"... it was a test. Secondly, what woman invites a man in and serves him home made dinner and gets him a beer? She showing off man, she's know a man likes a woman that cooks and brings him beer! Long story short, yes she is thirsty and you a tall glass of water bro.
He'll if the falling out was that bad she probably puck you just to piss off your baby momma.
