If you're still good friends with your ex, then maybe its bettet to tell him first, before he finds out through his friend.
Otherwise it could hurt the friendship you two have, and of course that will only make issues arise, which will end up hurting both people.
Do the right thing, be honest and tell him. He'll probably not take it well, but being truthful is better than trying to hide it. The truth always comes out eventually. It's better sooner than later
Tell him. You've already betrayed his trust once so withholding that info from him will be like betraying him a second time. It's best to be upfront and honest with him from now on... even if honesty hurts him.
