<human>: Can you provide a brief overview of the text?

We have been going out for 7 months, and she has always had a problem with checking out guys even in my presence. This last time she checked out a guy we were on our way to see The Hobbit. I didn't say anything when I caught her to avoid problems since it was our first hangout after two weeks of studying for finals. The next day when I bring it up she admits to looking at him and explains she only looked at him because she recognized him as a classmate. She later admits that she was checking him out, and then she stubbornly admits that she has checked him out before. I question her further, and she finally explains that she did it because he is attractive and she would wonder in class whether he had a girlfriend and if he had a nice body.

Its eating at me inside to know that she does not love me enough to have eyes only for me. She claims she loves me and that those were only thoughts and that she would never do anything with anyone but me.
