I have nothing to say but that I was very embarrassed for Prudie, who used this letter for her Tourette's-worthy spate of puns. Not appropriate, not funny, not helpful, not entertaining. Just sad.
I say you should go to the nearest barber and collect some hair clippings. Place in bag and give. Maybe she'll get the point.
I say that my first reaction is that yes, anyone can choose their friends, and it's time for you to unfriend this bride and skip the wedding. But Prudie is right that she did end up theoretically happy, and she doesn't need to let the past influence the present. I would add that LW expects her friends to forgive and accept her husband, who was at least as responsible for the affair. (Has he apologized to any of them? No? Then he's on the same footing as the OW.)
I say: yeah; But how can't you love the law? It's really interesting intellectually, morally, etc. etc.
