A couple of things jump out at me from your posts. You will not be able to find a good balance of nice vs pushover or kind vs jerky if you are trying to determine what women want and using their desires as some kind of measuring stick or goal. Do your best to be what God wants you to be, and any reasonable woman will want nothing else for or from you. I know that being what God wants you to be is easier said than done, but it seems to me that you're largely overthinking it because you're approaching it from the "how do I be what women want" angle. But of course that's a confusing thing to figure out, because every woman wants something different... and besides, women (humans in general, because humans are flawed and sinful, but I say women because of the context) will sometimes want things that are selfish or unreasonable. That doesn't mean that you should do or become that thing just because it is what a woman wants.
But all of this honestly is more simple than it seems... generally speaking, we know what is good and right and pure and proper. If we don't, we ask God for wisdom. And there are a ton of specifics in the bible, too: Be slow to speak and slow to anger, but quick to listen. Be patient. Kind. Do not seek your own, so do not be manipulative or selfish. If you notice selfishness in something you do, take it to God. Ask Him to change you. If you notice pride? Do the same thing. Any one of various other fleshly attitudes? Do the same thing. Be conscious of your actions and ask God to search your heart and make your motives right. God will answer prayers for personal growth. He wants us to be what He told us to be, and He will absolutely help us do it. And maybe there's even someone in your life that you trust, an older guy at church perhaps, that you could ask for input or advice about what to work on.
I am going to be blunt here: if you think this book is responsible for the recent changes in your attitude, then I think you should throw it in the trash. There's a reason why you are not at peace with the latest version of yourself.
