JacT, I feel for you, especially after 28 years. (Though being in this sitch after 16 doesn't feel any better.)
Daddy, can you point me to any threads that go into details about "affair bursting"? I'm definitely in that sitch you describe right now: H clearly hasn't been straight with me (looks like this OW might have been around longer than I first thought) and he's certainly made up his mind right now. No effort on his part at all to contact me or ask about his son since he last saw him on Sunday. I know that's only a couple of days, but this is a man who dotes -- or, at least, has doted -- on his son (who's an absolute sweetheart).
