Well, Easter is a day that now lives in infamy in my family...
Damn that's a good read
Earlier posts are spot on Pass, don't tell him where you got the info.. he's just going to lock it down if you tell him or dismiss it if you show him any print outs. He just wants to defend his territory now, you can't win that battle so just back away from it.
OW and contact? If you think it will do damage to the affair and break those two up I am all for it... but be careful as OP can be very arrogant when you confront them, and you won't get an ounce of pity.
Excellent work though... excemplary confrontation there.
