The position has to repeat 3 times or 50 moves without a pawn move or capture for you to be able to claim a draw. It's not a rightful draw until one of these happen, and winning on time in this sort of situation is just part of blitz chess.
The position looks winnable to me for white (not much analysis), just hiding the king behind the black pawns, or blocking a check with a pawn.

And if my opponent has the edge I expect him to do the same to me.
This was the final secquence of moves in a game of 5min blitz I just played. I was under time pressure and my opponent just kept on playing those moves. I offered a draw and he declined and eventually he won on time. somehow I feel cheated out of the rightful draw it should have been.
arn't there rules concerning this?
