Did Pushkin have a love affair with some peasant girl before to marry?

Ι believe I read somewhere long ago that Pushkin had an affair with some peasant girl which he abandoned before to marry his wife Natalia.
Also I think there is amongst his books someone with a subject similar to this event (the affair with the abandoned poor girl in the country).
I do not find anything now when studying his biographies in the net.
Maybe I imagined that?

It's a well know fact that Pushkin was a terrible womanizer- he had a huge number of affairs. One of his most famous ones was with Anna Kern to whom he dedicated a lot of his poems. In fact, if I'm not mistaken, Pushkin has caught a veneric disease from one of his adventures :)

Would be surprised one bit if he had an affaie with a peasant girl...
