It seems to me like this could get on a better path. RIGHT NOW! If I were you I would start being honest. Tell your partner you have heard from this man, what he said and how you feel about it. Tell him you intend to have integrity from here on in and what you plan is to do so. I would figure out a plan first on how to live life more honestly though. The foundations thread might help with that. Try a tag search on "foundations" to find it. I know its scary, but look where fear got you last time. It caused lack of trust in your relationship and almost made you loose both of them. I think I would opt for walking through my fear and see what happens. You don't have anything to lose at this point.
