We need to be careful about jumping to conclusions without any hard evidence. Yes, the OW has moved to H's office and your convos with him has tampered off drastically. That is something to be mindful of for sure.
Your different game plan going forward is to say absolutely nothing about the OW. Put on a new shirt, shoes, dress, pants/slacks, perfume, lipstick or some other item each time you and H do the kiddo exchange.
Be completely nonchalant when you talk with H. Keep your convos short, to the point, and be the first person to leave with a jaunty walk of self-confidence. And do not even try to glance back at H when you walk away.
