My in laws love me. They have stated that they want us to stay together. However, my father-in-law had A's in the past. The OW concept is a very familiar one to my mother-in-law, but in her words "He's my son and I love him and will never turn him away" She asked him point blank if he was planning to visit her or vacation with her and he told her "No." I have a copy of the flight info and the airport is 45min from her house, he has no hotel or car reserved. He must think I am stupid.
I think you should re-expose this latest development to the in-laws. I'm sure they won't appreciate that their son is flat-out LYING to them. Don't dwell on it; state it, and let it go:
"I understand that you love him, and I do too. It just makes me very sad that he's lying to all of us, and going to visit her in CT when he flat out told us all that he wasn't. I can handle the infidelity actually better than I can handle the deceit and the disrespect."
