Not your job to reveal this to him. It can only create tension and general badness. Also she may have already told him about past exploits and he elected to keep it to himself

It depends on how close the OP and "Joe" are. If they're just roommates and/or have
only been friends for a few years/not that close, etc., then maybe I agree...

But if the OP and "Joe" grew up together or have been best buds for the past 10 years, etc., then it is his job.
