Dude dont listen to maleficent... please.

This is exactly what happened to me... in the reverse. A friend of my old gf kissed her. She didnt kiss back, in fact she never talked to him again after that. No harm, no foul.

The problem was she didnt tell me at first. I didnt know this guy, hell we lived over an hour away from each other so chances of me ever seeing him are non-existant. But my best friend, his gf, hell even my sister found out... because word spreads. So there I was, everyone asking if I was ok, asking if we were still together, and like a retard I said "why not?"... and sat there baffled by their weird look.

She sobbingly confessed over a week later.. by then I had found out about it. I didnt give a SHIT about the kiss, what enfuriated me was that she didnt tell me about it. The lesson? something stupid that wasnt her fault turned into her cheating on me and then lying to me. Yes lying because she made a concious decision not to tell me.

Take it from me, I would have been mad that she put herself in that situation (as I'm sure she will be to you), but that's a far cry from the hurt, anger, and gaping wound in her trust of you that not telling her will create.

You're not a bad person, maybe a little dumb/naive for letting it get to that point but nothing bad. Just make sure when you tell her about it, ensure her that you will never talk to that girl again (state it many many many times), and that you will never put yourself in a position to hurt her every again (and state this many times as well).
