Gold Protoss having trouble with Terran in early/mid game (replay)

Here is a link to my most recent ladder match. http://bit.ly/mFi5G8

I know my forcefields weren't the best, and my +1/charge was just finishing, but I really feel like the battle shouldn't have been as one-sided as it was. I could have used more zealots in my composition, but I don't really know what else to do differently. It's getting extremely frustrating when I lose that decidedly to opponents that don't even bother scouting me.
