Hush she is the brightest in the leaf, she knows everything.
Sakura is needed. Naruto is stupid
Sakura had time to reflect and think, she knows the good and the bad of love. There is no formula to love but she knows it.
Sakura seemed not to know about love because everyone was forcing naruSaku down her throat for the majority of the managa
No bambina.
She had no time to reflect on love. Love is something that is cherished in a pair of two (most times, hopefully). Sakura 'loved' Sasuke, but Sasuke hated Sakura. He might of had strong feelings for her before Part One ended but soon Shippuden started it was obvious he had no feelings for her.
You can only reflect on love when you are currently in love and the person you love, also reflects the intense feeling of deep affection. Even After the Manga ended Sasuke left to go 'soul searching', so they're love never existed. You cannot love someone without first getting to know them through countless years of being together, struggling, and pulling through when things turn sour.
That's why Naruto and Hinata are expericing this love. Because Hinata has feelings for Naruto, but we are seeing Naruto starting to express his own feelings for her aswell. That is the beginning of 'love' but it won't be complete until many years of experience.
SN; Sakura pushing relationships, feelings, and/or emotions is a standard Kishimoto joke. She knows nothing but a one-sided deep psychotic relationship.
