Get a large towel and fold it around the pillow. Have your husband take one end of the towel while you take the other end. Twist the ends of the towel to squeeze and wring on the pillow. (Think of a piece of candy in a wrapper. The ends are twisted with the candy in between.) You won't be wringing the pillow directly so it won't misshappen. When you are done wringing, gently work the pillow back into shape. I would then try OneandDone's suggestion below to get the last of the water out. Finally I would put the pillow in the sun to dry and air further. You might need to rewash to get out the moldy water smell. I don't think you've ruined your pillow. I think you just didn't get the water out well enough despite your efforts.
Alternatively you could put it in a very good dryer. Mine has a no heat, low tumble setting which I use on heavy comforters and pillows. One last suggestion would be to restuff the pillow. You could pick a seam apart, restuff, and then hand stitch closed. I had to that with one of my grandmother's pillows I couldn't get the smell and lumps out of. Good luck.
