Help!

Okay this to some of you may sound childish and pathetic but to me 😂 I’m struggling here and I need advice from other woman.

Anyway so I’ve had a crush on a guy two years older than me he is literally the definition of a Greek god he was designed and made to break girls hearts everywhere he goes! sometimes we walk past each and he smiles or smirks at me (which make me melt ! Btw) and other times I catch him looking at me out of the corner of my eye. so I was wondering if anyone had any advice or tips for me that may help and I’m also really scared that I’m not going to be enough because he’s used to girls older more experienced and girls who are willing to put out more
