TLDR: how to take feedback/advice from a girl you are trying to attract? Do you show that you are listening to her advice and working on bettering yourself with it? Or does that make you lose value and become unattractive? Do you show that you care about her opinion or does that put her on a pedestal?

Context: (can skip, or read and provide general advice)

This girl and I know each other REALLY well, we talk almost everyday etc, we flirt occasionally and she’s dropped some hints that she’s interested but I wasn’t. Lately i think she lost that interest and I found myself changing my mind and feeling attracted to her. I’m now finding myself aware and nervous about everything I say/do around her (whereas I didn’t rly care before). Since we know each other well, she knows my flaws and gives me advice sometimes on how to improve as a person in all aspects. How do I react to this advice? Do I give it attention and implement it and show her that I care what she thinks?

Thanks for your time :)
