Well , Here's my opinion.
This might work in the short term. But in the long term it will lead to divorce.
St. Mary's is not as backwards as it may seem and swapping has been known to happen here.
Of the cases I know of or have heard of, those involved ended up with different partners and the swapping stopped.
St. Marys is also a County where if you get involved in adulterous behavior, you may as well put it in the Enterprise. (which no one reads, but you get the point).
I believe we once had a Governor who got involved.
