Does he know you are part of that forum? If so ask him what the heck he's talking about. If not, it might have a creepy, stalkerish vibe to admit that you had read it.
It has been my expereince that where there is smoke there is fire. I dated someone in college that I always thought was cheating on me. All of "our" friends said I was CRAZY! Well guess what - when we broke up I found out he was cheating on me with anything in a skirt he could get him hands on! It was unbelievable. I was also shocked at how many people told me after we broke up that they were glad we had broken up because I seemed like such a nice girl that they couldn't imagine what I was doing with him!
