Re: Spying on your spouse, not such a good idea!
Having been on the receiving end of spying, I'll say that spying really doesn't make a difference in the mind of the person doing the spying. When they're doing that, they've already made up their mind, and it's only a matter of finding the evidence.
And there are only two possible outcomes in the mind of the spy - either, a) he/she was cheating or b) he/she hid the cheating too well.
I never cheated on her, though. But I never got an apology either.
But not only did she commit a felony, by reading my work emails, she put me in extremely difficult position. At least they never found out at work.
Now, from purely pragmatic point of view, do you think committing a felony is going to help or hurt you in case of a divorce?
