Umm, source? I am pretty sure it's a troll or KiriAsu hater doing.

As for your question about what happened during those 200 years, there is the story "Cradle of the Moon"

Also, next volume of light novel (#19), that is going to be released in February, will cover that story.

Once again, Kirito is ONLY in love with Asuna and stays faithful to her. You don't have to worry.
