You made it the right choice. Most marriages end up in a dead bedroom situation.
It is more than that; in Western democracies, the moment a woman decides the marriage is over, for whatever reason, she has the full support of the legal apparatus of the state.
It goes back to the adage, "Men pay for it one way or the other."
I have chosen the other. I am on here and pick and choose when I want it, and with whom. At the end of the transaction, I go back to my private life. It may sound somewhat cold saying that, but there is nothing colder than a wife who has decided she has had enough and no longer puts out.
