Nonononono. You're totally off tracks there.

You completely forgot to make the mapping of female
responses, where yes means no, no means maybe, maybe
means when hell freezes over. Plus you need to take
into consideration the sarcastic and testing questions
where you need to determine whether the question is
rhetoric or something that requires a followup-question
as an answer.
And you also forgot to add the automatic recursion testing
for questions like 'Do you like the color of our sofa?',
where you need to iterate that no matter what you do or
say, the end result is you and her in a furniture store.

Just balancing <> of happy doesn't do the trick, I'm afraid.
