Perhaps your H and OW have run their course.

Or maybe he's trying to reconnect with the family - I read somewhere that MLCers do reconnect eventually with family, friend and the wife being last.

I wouldn't ask though, let him tell you if he wants.

And as we know we have no control over their actions. Remain calm as you have done so far you're doing great I think
