Go ahead & confront him in a very diplomatic way.........like.....

"I heard from Amy.....,..just wondering your side so i have all the facts from both sides".

As it stands you don't really have a relationship if it's in secret..so you really won't be loosing anything if it doesnt tirn out ok...& if it does then it will strengthen the communication in your relationship.

You really have nothing to loose by communication...i wouldn't go into it as a confrontation however
