Heads up 20+2 / to aggressive?

[TheRonin]

Do you think I played this hand too agressive heads up?
I dont think I would have pushed here but the last couple of times I got heads up the blinds eventually increased up to 1,000 -2,000 at which point the skill factor goes completley out the window.
Thanks for your input
