Don't confront him about the trip. In fact, don't ask ANYTHING about the trip. Just tell him to have a good time. Don't call him. Don't text him. Nothing.
Your H seems to be acting extra nice lately. He's probably doing that out of guilt. Don't eat from his hand. If he does something nice, don't overly thank him or anything. Just say 'thanks' and act like it's no big deal.
Is there anything you can plan for yourself while he's gone? Something fun? Put something on the calendar so that he could see, but be vague.
