I can understand your feelings about the cheat Mani. I'd feel exactly the same. On one hand my first reaction was that the g/f should know because from what you said she must think he's single and think they have a future together when he's just stringing her along. I wouldn't tell the wife because that could end up breaking up the family which if he dumped the girlfriend and the wife never knew then maybe the family would be OK.

On the other hand if I were the wife and I'd been cheated on and later found out about it I'd feel like my whole marriage from then on had been a sham even if he'd tried to make it work.

Then on a totally different hand (yes, I've got three hands this morning) I think that for your sake you'd be better off keeping out of it because you could end up being seen as the trouble maker.

You've told him what you think of him and what you thnk he ought to do and that's probably as far as you should go.

Maybe the wife will see him with his g/f somewhere and the whole thing come to light that way or maaybe he'll just dump the girl eventually anyway and carry on with his family as if nothing had ever happened.
