$100K is chump change to Smitty.
Marriage is stupid for reasons like this and excessive alimony. You sign a paper and all of the sudden you're trapped under all of these archaic laws that are designed to fug males.
I'll play devils advocate and say this, sex is the most addictive drug in the world and pussy can make men do things that most may not consider to be normal. these two obviously had some sort of sexual chemistry and she was obviously not happy in her marriage, and perhaps Smitty was bored in his now that the kids are grown and he's having a mid life crisis - he got caught slippin.
he'll pay this fine and that dude will live the rest of his life not feeling like he's enough. The chick will prob strike again or be ready to settle down, who knows or cares. Smitty will prob go through a hoe phase for the first time in a long while and then settle down with a young chick that he can ride into the sunset.
everyone makes mistakes, everyone loses in this situation, life goes on, do what makes you happy.
