I get jealous so easily. It kills me that you're best friends with other girls. It kills me seeing you happier with them than you are with me. It kills me knowing that I can't give you what she has. I know she's your best friend. I know you've known her longer than me. I know you guys have a history I can't compete with. I know she used to like you. I know you used to like her.  I see the way she looks at you, the way she asks for you, the way she says your name.  I see how your face lights up whenever someone mentions her or whenever she walks by.  Whenever you talk about her.  You have so much more fun around her, I can tell. I get jealous when you guys hangout by yourselves. So jealous I get sick to my stomach. Like I am right now. It hurts. It hurts so much. I just want to tell you but I can't. I have to keep these feelings to myself.
