My H left claiming he'd been unhappy for the past 30 years. 7 months later S19 caught him with OW (he doesn't know we know). I filed the next day on the grounds of adultery (necessary in my state) so his secret will be revealed. He's still hiding her from the kids but they all know and aren't happy with him AT ALL. I haven't spoken to H in 6 months so if this happened to me I wouldn't say anything. What good would it do anyway? He's just going to lie because that's what cheaters do.

FWIW secrets almost always come out eventually. smile
