I'm sorry, Unicorn. I'm glad he got out quietly and without a fuss--and that he didn't try to lie his way out of it. Please resist the temptation to ask him about your prospects with younger guys. I know the feelings you had for him were real, and it's great that you see it as a pleasant experience rather than a mistake.He knows no more about other young guy on the street would. His responses will just hurt you.
Just be careful with the hotel. Most demand a credit card for incidentals, even if you have prepaid. He could raid the minibar, order tons or room service, etc.
