Calm yourself, little girl questions mean nothing. glances are nothing. Don't start getting all high and mighty thinking he's thinking of you. You're nothing. You're nothing in his eyes but a flirty little girl.
He doesn't seem like that? Well, have you ever thought of what you seem like to other people? Well it's nothing like you are.
Just remember, you're no priority in his life until he proves such.
Don't make him important if you're not that important to him.
