Will Asuna And Kirito Break up in season 3?

Definitely not but Asuna will still have rivals.

I really hope not, they are my お気に入り animes couple, they definitly should get married, what would make sense after the Ordinal scale movie :)

Absolutely not.

I don't think so because Kirito risked his life for asuna in SAO and ALO and even after that.He wanted to see her no matter what and wanted to save her.So does asuna.If Asuna never loved Kirito than she would have dated that fairy king guy.So I hope they don't break up
