Why wasn't it a draw?

Hello, I played a blitz game, got winning postion, but with only few seconds on the clock I decided to go for a draw by repetition of the moves. We repeated the moves and I lost on time. Here is the game:

Why wasn't it a draw?

I guess if it is a check, it will not be a 3-time repetition. So good luck in later games!

It wasn't a draw because you didn't hit the draw button. Even if it is a draw by repetition, the chess.com server will allow the game to continue until 1 player clicks the draw button. When that happen's, the server will end the game automatically. The server does NOTend the game automatically for you. I learned that the hard way.

Thanks zugzwangrulz for explanation!  Next time I will click the draw button.
