Alright, so I think after reading back over all of the posts, I can boil most of everything down for the OP.
From the ladies' standpoint, you should come clean no matter what. No surprise here.
If your wife is super-chill, open-minded, smokes weed occasionally (or all the time), and/or is deaf, mute, and blind, AND you are 100% certain that even if you did split up it would be on friendly terms, then tell her.
If your wife is super-chill, open-minded, smokes weed occasionally (or all the time), and/or is deaf, mute, and blind, AND you are 100% certain that she would become a vindictive man-eating bitch if you split up, then do NOT tell her.
If your wife is unforgiving, stuck in her ways, and won't listen to reason no matter how reasonable it is, the do NOT tell her.
If your wife is actually your "partner" and he is overdramatic and neurotic, send all of your shit to me and go hang yourself.
Bottom line is, it is a personal thing and it's sad that this thread ever degraded into an argument, because each and every one of us should know our own wives and situations better than anybody else. So after reading all of this, you should have an idea of what you should tell your wife the
next time it comes up, because we all know that your answer this past time was "Whaaaaatttttttt??????? Pshhhhhhhhh! No way!!!!!!!!!! Me?????????? Of course not baby!!!!!!!!!!! [nervous laugh, sketchy eye contact, quick change of subject]"
