Was a draw the right result?

In this game, I found myself in a position where material was equal, but I felt that my position was inferior to Black's. My opponent's king safety and pawn structure was stronger than mine, and his queen was really well placed. I had an opportunity to force a draw by repetition, and I wasn't sure whether it was the best decision for me in an otherwise losing position, or a cop out in a game that I should have won. I took some time to work out what might happen if I don't repeat, and I decided to take the draw.

What are your thoughts? Did I miss something, or was this a lucky escape in a game I should have lost?
