So, wait a sec --
You're lying to your wife about many things, and they're things that actually matter. Not playing MMOs, or going to the bar, or whatever. You're unfaithful and you're not only proud of it, but you've actually convinced yourself that she is responsible for your infidelity. Okay, takes all types. Whatever. You're an adult, you make your own bed. The part that gets me, though, is this:
What fantasy world are you living in where you don't think that you haven't already fucked them up 10 ways from Sunday? Don't you think they see what you're up to? Or are you one of those parents that thinks something like "oh, they're just kids, they don't have any clue what's going on"? They probably know everything you're doing. If they don't know yet, they will. What's your plan for that one? Gonna teach them about frequenting them pizza places, bro?
I think they'd be better off roughing it without you and your money.
