In love with a girl?

The truth about her

-I...I'm so sorry R..R...Roseluck I didn't meant to bump into you...
She looked mad and she went away from me real quikly.
Right there I didn't really cared, I just wanted to find Rainbow. I went out to the soccerfield and there she were. When I saw her I got butterflies in my chest. She shooted fotballs into the goal. Her hair was stunning when she ran. But her tiny fotball shorts looked pretty stupid. I started to laugh uncontroleable and when she was going to shoot a ball into the big goal she heard the laugh and instead she turned around.
— So first you are hitting me, and noooow you are laughing at me? She smirked.
— I'm sorry Rainbow... for everything. The truth is that I just want you back...
—want me...back ?
— Back...to normal...
she stared at me and her cheeks turned warm in a light shade of red.
— Don't you get it... she mumbled and looked to the ground.
— ah really don't Rainbow...
— I like you... she looked away
I stared at her and I felt my cheeks getting warm as well.
— But...But you told me you were just into...guys? I smiled confused
— I LIED Aj...I'm gay... she breathed slowly.
I went in for a hug and hugged her gently.
— Oh Rainbow... Ya didn't had to lie for me.
Rainbow smiled a bit still blushing.
— Applejack...
— Mhm?
— That slap was sooooo awesome! you're stronger than I thought!
We started to laugh and then we went back into the school.
But I couldn't concentrate at anything except for Rainbow... Am I in love with her? Or am I just not. Am I gay? Am I bi? Or straight?
