I think you said it all right there. (I took some stuff out, though.) How ever you go about doing it, she'll probably take it hard. Break ups are always hard. But I think the truth is your best bet. IM me later and we can talk about it. I work today, but I might be online on msn. IM me there (same screen name as here)
This sort of thing happens. People grow, and not always in the same direction. You say you feel like a pig... Did you go into this with the intention to deceive her? Did you pop her cherry then a week later decide to move on, or have you been sexually active with her for a while, but now the relationship is not what it once was? A pig goes in with the intention of getting some, even if he has to deceive her to get it. A pig goes for the chase, and once he gets what he wants he starts looking for a new target. From what you've posted here, you don't sound like a pig. You sound like a normal teenager. All you can do is be honest with her. Yes, you will probably hurt her. However, every time anyone I know has dragged things out because s/he didn't want to hurt the other person, that other person wound up getting hurt much worse in the end.
