You handled that with about as much integrity as I have ever seen someone do. I am a pretty straight-n-narrow kind of guy myself (even more-so than in days gone by, before I became a father), and even I don't know what I would have done -- especially with such a "dish" served up... on a silver platter.
(On the other hand, given how shell-shocked I am from my W's underhandedness, the W's cousin connection would have me thinking set-up.)
Dude, you are such a stalwart, faithful guy -- your W is nuts to not cherish that in you. I thought that's what women really want and need in a husband. Man, what is it with these WAW's?
I know I am a rookie and all -- just passed 250 days last week. But I have considered giving my W the Ultimatum; I am starting to feel that at some point I will not be able to hold out for her much longer. Frankly, I don't know how I am going to make it a year, and I keep praying to God to give me the strength.
