The problem with the first one is that the beautiful bride is entirely too washed out. Way overexposed to be using a 'glow'. You wanna capture the details of her beauty, not make her look like she just died and is now an angel leaving for heaven. (sorry for a morbid example).
The second looks good, but it's overdone. A good way to accomplish what you're aiming for is to play with the levels to make sure the shadows and lights look the best they can, then duplicate the layer, and gaussian blur it 1pt. then overlay the blurred layer. IF done to the right picture, it looks uhhhmazing.
