I'm not sure if you've noticed it or not, but this feeling you are feeling, it's called being in love. you know because going even a day without their perfect smile is too long and everything about them appeals to you in a way it never has before.
Don't worry, you're in love if your heart dances to a different beat when they say those words and if your soul giggles when they are beside you, you really know you're in love then. I'm not sure if you noticed it or not, but this feeling you're feeling right now is what they call being in love.
