Also, and most importantly, don't worry about what she says right now. Don't worry about if she's comfortable with it or not. You are NOT trying to be the man you think she wants you to be, you are trying to simply be the best you that you can be. You already know or can identify the areas where you can improve yourself. Just do it. If it isn't genuine change to make yourself better no matter what, then yeah, she's going to see through it and believe it to be superficial - because it is if you're only doing it to please/impress her.
