Declaring it a “very brutal way” for his wife to find out, he believes that there could’ve been a chance of the marriage continuing had he been able to “talk to her rationally.”

I’m not sure if he means he could continue his behaviour without being caught or if he planned on lying and saying it was a one time thing. Either way I highly doubt he had any plans to be honest.

The “talk to her rationally” bit is hilarious. Yes I’ve been expensively unfaithful, have possibly been exposing you to a number of diseases without your knowledge, and have been physically unavailable regularly for years. What self respecting person wouldn’t “rationally” see that as perfectly acceptable! /s
