OK.  Have two good friends who are married to each other.  Rumour has it (and things are definitely adding up) that he's seeing someone on the side.  As it lies now, there is no concrete evidence that any one of us has to say that he is cheating, but there are enough signs.  The thought is that if he cheats so close to home then one of us will tell his wife about it therefore saving him the job and giving him the opportunity to look like the good guy when she leaves him.  Problem is, none of us are going to get involved until we are sure there is something to get involved in.  Don't want to rock an already unsteady boat.  She is adamant there is nothing going on, or is she denying all knowledge?  Who knows?  What should we do? On a more personal level, can a tongue fall off from being bitten?!  Reckon mine's on it's way out...balsamic vinegar didn't help either...
