But let me reverse the situation for you,. Is there any circumstance where you would do to your wife, what she did to you
You have to understand that relationship issues are 50/50. You have just as much responsibility in how you got here as she does. You were just blind to the issue, just like the rest of us.
The ladies here are dealing with your hypothetical. Their H's needs were not being met. They went to another person to get those needs met.
I don't have "real" numbers but this is my perception:
65% of the poster are left behind husbands with 99% of them having nice guy and beta behavior. 25% are left behind wifes 9% are wayward wives 1% are wayward husbands.
"Nice guys" would not do this to their W, ie all of the male poster here.
