this sounds very similar to my situation last year. i was playing mr nice guy. trying to accommodate her. i found that its not what you say but how you say it that makes the difference.
instead of saying "whatever works best for you" instead try taking a little time before answering her. slow down the game. take an hour or so before answering. instead of telling her your schedule "im working from home all week" be a little more mysterious.
example: W: no school next week blah blah
Me: (an hour + later )i can watch them during the day next week
W: oh, ok great, are you off? or working from home?
ME: (no response for an hour + or even hours) yeah, im working from home.
ive found, that the more you slow down the game, it makes her wonder. the less details you freely give, she has to ask for them. i can see that you are a great guy, a nice guy. STOP !
take it from me. I kissed her butt for a year and it got me nowhere. you dont have to be a jerk. but slight adjustments can make all the difference. btw, im no expert. but i have failed by doing exactly what you did.
