Wants to kick out third wheel

<p>I have a friend. She follows me EVERYWHERE because she is my shadow and has very low self-esteem. She's also really sensitive and I've tried telling her off, but she'll just start crying and calling me really mean and stuff (me? mean?? omg, I am like the nicest person in the class for crying out loud). And I like this guy in my class, and we've been friends for a while. Here's how he flirts with me: he'll like make funny jokes and dadadala, you know, take my stuff and stuff, and we'll end up talking. Here's how I flirt with him: I'll make jokes back, yadayda, playfully kick him for taking my stuff, and we'll end up talking. Pretty insane, I know. But here's the problem. Sometimes, I just wanna be ALONE with him, but my shadow FOLLOWS me when I'm flirting with him, and then after he takes my stuff or whatever playfully, she'll copy me and kick him! It's not like she LIKES him, but I just need my damn space!!!!!!! OMG, can't she see that I need alone time with OTHER people sometimes???? For the love of God!!! What should I do? :(</p>
