Do you think I should ever tell my wife about the long ago prank?

On July 10, will be 8 years that I was going to prank her. However, after watching how it all got serious too fast and her happy expression... I couldn't follow through. I stopped the video halfway. It doesn't exist because I deleted it. I realized my love towards her at the same time and it became real, no longer a prank.

Till this day, no one knows about my attempted prank, not even my friends, no one. Do you think I should ever tell my wife about it? Or is one of those times that should remained unsaid. Or is it pointless to even mention about it by now since it became real and we have a daughter.
