I couldn't help myself. If it was me I'd write on my facebook status that the person whom spread your news was a selfish cow that had no respect for your friendship etc and that it was your news to share when the time was right and you hope they enjoyed spreading it when it wasn't there news to tell. People whom might have spread your news will know who they are without you pointing the finger and risk not having it right. If it was someones guess then no harm done.
